Description

  The present invention relates to a merchandise sales data processing apparatus and a merchandise sales data processing program for discounting a predetermined amount when a set sale is established when a set sale is established by combining single sale products sold separately.

  In a store such as a convenience store, a service is provided in which a predetermined amount of discount is satisfied when a predetermined number of products are purchased within one transaction, and the discount establishment condition is satisfied. Such a service is known as so-called M & M service processing or set sales processing. The M & M service process is executed with the discount establishment condition that the different number of target products have been purchased for each established number, and the set sales process is executed with the purchase condition for the same or the same type of target product as the discount establishment condition. It is common.

In addition, in a product sales registration data processing apparatus such as a POS terminal that performs data processing of such discount services, the set sales that are most advantageous to customers are surely established regardless of the product registration order, and unfairness is eliminated. The thing is known (refer patent document 1).
Japanese Patent Laid-Open No. 9-91547

  By the way, among the products sold in stores and the like, there are pack sales products that are sold in units of a plurality of single sales products that are sold separately. For example, it is a case where 6 cans of beer are sold as one pack, or a case where 20 boxes of cigarettes are sold in one pack (ie, one carton). As described above, in a product sold as one product or as a pack, a product number given to a single sale product constituting the pack is different from a product number given to a pack sale product.

  Also, the discount conditions for set sales as described above are set in a table etc. in advance for the combination of the product numbers of the single sale products to be sold as a set, and set in the table with the product number read from the single sale product to be sold It is determined whether or not set sales have been established from the combination of the product numbers to be sold as a set.

  Therefore, when registering a plurality of types of products including packed product for sale within one transaction, the product number of the single product for sale and the product number of the product for sale are different. Even though the set sale is established, the discount condition for performing the set sale is not established, and the discount cannot be received. For example, if you buy 1 canned beer for 230 yen and 1 chicken for 180 yen in one transaction, it is sold as a set with a discount of 60 yen, that is, the product number given to the canned beer And the product number given to the chicken, if the customer purchases a pack of 6 cans of 230 yen canned beer and 1 chicken for 1 transaction, Since the product number given to the pack is different from the product number given to the canned beer, the discount condition is not satisfied and the discount cannot be received. This can cause the store clerk to receive complaints from customers.

  By entering the product number of a single sale product that makes up a pack and registering the product by multiplying the number of products in the pack, the conditions for establishing a discount will be established for the pack sale product. , Can solve the situation where customers can not receive discounts. However, this increases the time and labor of the clerk who registers the product, and it is necessary to thoroughly perform the operation for all the clerk on the store side, which increases the burden on the store side.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a product number given to a pack sales product in which a plurality of single sales products constituting a set sales product to be sold as a set are configured, and the pack Even if the product number given to the single sale product that constitutes the sale product is different, set sale can be established using the product number given to the pack sale product, avoiding the situation of receiving complaints from customers Another object of the present invention is to provide a merchandise sales data processing apparatus and a merchandise sales data processing program that can reduce the burden on the store side.

  In the first aspect of the present invention, a set sales product obtained by combining a plurality of types of single sales products sold in a single unit is set in advance, and set sales are established by a combination of products traded in one product sales transaction.

It is determined whether there is a product number of the pack sales product set in the third table, and if it is determined that there is a product number of the pack sales product, the single sales product constituting the pack sales product is indicated. The product number is acquired from the third table, and based on the acquired product number and the product number included in the registered product data, it is determined whether the set sale set in the second table is established, When it is determined that the set sale is successful, the discount amount set for the set sale product in the second table is calculated based on the unit price included in the product data registered by the registration means. The is intended to discount from the transaction total.

  The second aspect of the present invention is a function for causing a computer to input a product to be traded in one product sales transaction, and to input the product data of the input product, the product number and the unit price of the single sales product sold separately. A function for reading and registering the product data including the product data including the product number and the unit price of the pack sales product in which a plurality of product data including the same single sale product are configured, and the registered product data indicates A function for determining whether or not the product number includes the product number of the pack sales product set in the third table in which the product number of the pack sales product and the product number of the single sales product constituting the pack are associated with each other. If it is determined that there is a product number of the pack sale product, the product number indicating the single sale product constituting the pack sale product is obtained from the third table. Based on the function, the acquired product number, and the product number included in the registered product data, the product number is a combination of multiple types of single sales products that make up a set sales product that combines multiple types of single sales products. A function for determining whether or not the set sale set in the second table is set based on the second table, and the discount amount when the set sale is established is set in association with the set sale product, When it is determined that the sale is successful, a function of discounting the discount amount set for the set sale product in the second table from the total transaction amount calculated based on the unit price included in the registered product data is provided. This is a product sales data processing program to be realized.

  According to the present invention, a product number given to a pack sales product composed of a plurality of single sale products constituting a set sale product to be sold as a set, and a product number given to a single sale product constituting the pack sales product, Product sales data that allows you to establish a set sale using the product number given to the pack sales product even if they are different, avoiding the situation of receiving complaints from customers and reducing the burden on the store side A processing device and a product sales data processing program can be provided.

The printer controller 30 controls receipt printing and journal printing by the printer 15. The scanner interface 31 inputs the barcode data scanned by the scanner 18.

  As shown in FIGS. 4 to 7, the RAM 23 of the POS terminal 1 includes a PLU table 41 constituting the first table, a set discount table 42 constituting the second table, a set merchandise table 43, and a third product table. Various tables such as a set product parent-child master table 44 constituting the table are provided. The contents of the data set and stored in each table 41 to 44 will be described in detail below, but the data set and stored in each table 41 to 44 is a predetermined time such as the time determined by the headquarters at the start of business. At this timing, it is delivered from the server 6 to the POS terminal 1 via the store computer 3. Then, based on the distributed data, the CPU 21 of the POS terminal 1 updates the data in each table 41 to 44 of the RAM 23.

  As shown in FIG. 4, the PLU table 41 prestores and stores product data such as a product code, a product name, and a unit price corresponding to the PLU number (product number) of each product to be sold. In this embodiment, the PLU table 41 includes “canned beer” (PLU number 001, unit price 230 yen), “chicken” (PLU number 010, unit price 180), “Frankfurt” (PLU number 011) as stand-alone sales products. Unit price 150), “canned beer pack” (PLU number 101, unit price 1380) is set and stored as a product sold in a pack. The canned beer pack is a pack sale product in which six canned beers with PLU number 001 are packed. In this embodiment, the PLU number is used as the product number, but a product code that can be read from a barcode or the like may be used as the product number.

  As shown in FIG. 5, the set discount table 42 sets and stores set discount data such as type, number of units established, discount amount, etc., corresponding to M & M numbers (numbers indicating the type of set discount). In this embodiment, in the set discount table 42, a set sale (type, set) is established with two products (established number, 2) in the M & M number 1001, and the discount amount at that time is 60 yen (value Set sale (type, set) with M & M number 1002 for two products (number of established items, 2), and the discount amount at that time is 50 yen (discounted amount, 50) ) Is stored.

  As shown in FIG. 6, in the set product table 43, an M & M configuration PLU number indicating the PLU number of the product constituting the set is set and stored in correspondence with the M & M number. In this embodiment, the set product table 43 includes an M & M number 1001 set of canned beer (PLU number, 001) and chicken (PLU number, 010), and an M & M number 1002 set of It is set and stored that it is composed of canned beer (PLU number, 001) and Frankfurt (PLU number, 011).

  As shown in FIG. 7, in the set product parent-child master table 44, the PLU number, the number, and the unit price of the single sale product constituting the pack are set and stored in correspondence with the PLU number of the pack sale product. In this embodiment, the canned beer pack (PLU number, 101) is a pack of 6 canned beers (PLU number, 001) (number, 6), and the unit price of the canned beer is 230 yen ( It is set and stored that the unit price is 230).

  In addition, as shown in FIG. 8, the RAM 23 stores, as one transaction, a buffer (registration means) that stores product sales data in which the PLU number is input via the PLU key or the like of the keyboard 11 for each product. Transaction buffer 51 for storing each data of PLU number, product code, unit price, sales point and sales price of each product to be sold by PLU number, and discount amount data and winning score data by M & M number when set sales are established A set establishment data area 52 for storing the transaction amount, a transaction total amount area 53 for summing the sales amount data stored in the transaction buffer 51, and a total amount of the discount amount of the set sale products for which the set sale was established in the transaction A discount total amount area 54 is formed. Further, the RAM 23 has a first PLU number area 55 for storing a first PLU number used in pack product discount processing, which will be described in detail later, a second PLU number area 56 for storing a second PLU number, and a pack. And a number of memory areas such as a work area used in the packed product discount process (not shown).

  Next, a description will be given of the main part of the processing when the pack sales product and the single sales product are traded in one transaction. FIG. 9 to FIG. 11 are flowcharts for explaining the processing in this one transaction.

  The CPU 21 waits for product registration (ST11). Here, when the input of the key signal of the PLU key of the keyboard 11 is detected, the merchandise number assigned to the key is registered, so the transaction buffer 51 and the transaction total amount area 53 are cleared (ST12). Then, the CPU 21 searches the PLU table 41 with the PLU number assigned to the input PLU key, reads the corresponding product code, product name, and unit price data (ST13), and acquires each of the acquired product name and unit price. Data is displayed on the display 13 with the touch panel and the display 14 (ST14).

  Next, the CPU 21 multiplies the transaction buffer 51 by the PLU number input from the PLU key, the product code read from the product table, the unit price, the sales score of the data “1”, and the sales price by the unit price. The sales amount to be calculated is written (ST15). In this case, when the data of the PLU number is already written in the transaction buffer 51, the current sales point number and the sales amount are added to the data of the same PLU number.

  Then, the CPU 21 waits for the next product registration to be performed (ST16). Then, as in step ST11, the key signal of the PLU key is input, and when it is confirmed that the next product registration has been performed (YES in ST16), the processes in steps ST12, ST13, ST14, and ST15 are performed. Repeat. On the other hand, if the key signal of the total key is input during standby for product registration (NO in ST16) (YES in ST17), the registration of each product sold and traded as one transaction is completed. The pack product discount process specifically shown is executed (ST18).

  First, the CPU 21 clears the set establishment data area 52 and the discount total amount area 54 of the RAM 23 (ST101). Subsequently, it is searched whether the PLU number registered in the transaction buffer 51 includes the PLU number of the packaged product (ST102). This PLU number search is performed, for example, by selecting one PLU number registered in the transaction buffer 51, and whether the selected PLU number matches the PLU number of the pack sales product set and stored in the set product parent-child master table 44. This is done by searching whether or not. By performing this process for all the PLU numbers registered in the transaction buffer 51, it is possible to search for the PLU number of the pack sales product from among the PLU numbers registered in the transaction buffer 51. The process of selecting one PLU number of the pack sales product set and stored in the set product parent-child master table 44 and searching for whether the selected PLU number matches the PLU number registered in the transaction buffer is set. You may make it carry out with respect to all the PLU numbers of the pack sales goods set and memorize | stored in the goods parent-child master table 44. FIG.

  Next, based on the search result, the CPU 21 determines whether or not there is a PLU number set as a pack sales product (ST103, first determination means). If it is determined that it exists (YES in ST103), The PLU number of the single sale product constituting the pack sale product and the number of the single sale product constituting the pack are obtained (ST104, obtaining means (acquisition of PLU number)). The acquired PLU number is stored in the first PLU number area 55 after clearing the first PLU number area 55, and the acquired number is stored in the number area 57 after clearing the number area 57.

  Then, the CPU 21 searches whether the PLU number stored in the first PLU number area 55 is the target product of the set sales product (ST105). That is, it is searched whether the acquired PLU number matches the PLU number set in the set product table 43. Based on the search result, the CPU 21 determines whether or not the acquired PLU number is a target of a set sale product (ST106). If it is determined that a PLU number that is a target of a set sale product, that is, a PLU number that matches the PLU number stored in the first PLU number area 55 has been searched in the set product table 43 (YES in ST106), the PLU number Correspondingly, the PLU number set and stored in the set product table 43 is acquired (ST107). As a result, the PLU number of another product that is combined with one of the individually sold products constituting the pack is acquired. The acquired PLU number is stored in the second PLU number area 56 after the second PLU number area 56 is cleared. When there are a plurality of PLU numbers set and stored in the set product table 43 corresponding to the PLU number, the plurality of PLU numbers are stored in the second PLU number area 56.

  Subsequently, the CPU 21 searches the PLU number of the commodity registered in the transaction buffer 51 for a PLU number that matches the PLU number stored in the second PLU number area 56 (ST108). When a plurality of PLU numbers are stored in the second PLU number area 56, one is selected, and the search is performed for the selected PLU number. Based on the search result, the CPU 21 determines whether or not set sales are established (ST109, second determination means). If it is determined that set sales are established, that is, if the PLU number that matches the PLU number stored in the second PLU number area 56 is in the PLU number of the commodity registered in the transaction buffer 51 (YES in ST109) ), Set sales are established with the PLU number stored in the first PLU number area 55 and the PLU number stored in the second PLU number area 56. Therefore, the CPU 21 stores the M & M number of the set established in the set establishment area and the discount amount corresponding to the M & M number and the establishment score “1” in association with each other from the set discount table 42 (ST110). When the set is established, if the number of sales points registered in the transaction buffer 51 corresponding to the PLU number stored in the second PLU number area 56 when the set is established is 1, The processing is excluded from the target of set sales. If the sales score is 2 or more, until the value obtained by subtracting the set score from the sales score becomes 0, the target to search for whether the set sales are also possible in the subsequent processing And As a result, it is possible to avoid overlapping sales.

  Next, the CPU 21 decrements the number stored in the number area 57 (ST111), and determines whether or not the number stored in the number area 57 is “0” (ST112). If it is determined that the number is not “0” (NO in ST112), the processes in steps ST108 to ST112 are repeated. By repeating the processing from ST108 to ST112 until the number becomes 0 in this way, it is possible to search whether the set is established for the number of single sales commodities constituting the pack.

  If CPU 21 determines that set sales are not established (NO in ST109), CPU 21 determines whether processing of the searched PLU number has been completed (ST113). That is, it is determined whether or not a process for determining whether or not set sales are established for all of the PLU numbers searched as other products to be sold as a set (PLU numbers searched in ST107). Therefore, if it is determined that processing of the retrieved PLU number has not been completed (NO in ST113), CPU 21 returns to step ST108.

  On the other hand, if the CPU 21 determines in step ST106 that the PLU number is not the target of the set sales product (NO in ST106), it determines that the number is “0” in step ST112 (YES in ST112). If it is determined that the processing of the PLU number searched in step ST113 is completed (YES in ST113), the processing returns to step ST103, and it is determined again whether there is a PLU number set as a pack sales product. To do. If only one PLU number of the pack sales product is searched based on the search result in step ST102, it is determined that there is no PLU number. If two or more search is performed, the PLU number of all the pack sales products is described above. After performing the processing of steps ST104 to ST112, it is determined that there is no PLU number. That is, since the above-described processing can be performed on the PLU numbers of all the pack sales products searched in the transaction buffer 51, even when two or more pack sales products exist in the transaction buffer 51, each pack sale It is possible to search whether or not a set sale can be performed for a single sale product. When CPU 21 determines that the search in transaction buffer 51 has ended (YES in ST103), it ends this packed product discount process and proceeds to step ST19 shown in FIG.

  Thereafter, the CPU 21 performs merchandise sales registration processing with the contents stored in the transaction buffer 51 and the set establishment area (ST19). Specifically, the product data stored in the transaction buffer 51 is read one record at a time, the product data is registered for each record, and the set establishment data stored in the set establishment area is read one record at a time. A process of registering set establishment data is executed every time. At this time, the CPU 21 adds the sales amount of each record in the transaction total amount area 53, adds the discount amount of each established set in the discount amount total area 54, and then adds the sales amount in the transaction total amount area 53. The total discount amount summed in the total discount amount area 54 is subtracted from the total amount (discount processing means), and the subtracted total amount is displayed on the display 13 with the touch panel and the display 14 (ST20).

  The CPU 21 determines whether or not a payment amount greater than the above total amount has been input using the numeric key and the deposit / cash key (ST21). If it is determined that the input has been made (YES in ST21), this payment is made. The difference between the amount and the total amount is calculated as change and displayed on the display 13 with the touch panel and the display 14 (ST22). Further, the CPU 21 creates receipt print data based on the contents of the transaction buffer 51, outputs the receipt print data to the printer 15, prints the receipt print data on the receipt paper and journal paper, and cuts the receipt paper. Then, it is discharged as a receipt from the receipt issuing port 16 (ST23), and the drawer 17 is opened (ST24). Thus, the current one transaction process is terminated.

  When the customer purchases one canned beer pack and two chickens, ie, one canned beer pack and two chickens are sold in one transaction, the effect of one transaction processing of the POS terminal 1 configured in this way. This will be described below.

  After the customer puts a canned beer pack and two chickens in the store, the customer hands the store to the store clerk (the operator of the POS terminal 1). When the store clerk receives the sales basket, he / she operates the keyboard 11 of the POS terminal 1 whose mode is the “registration” mode, presses the PLU key to which the canned beer pack is allocated, and subsequently the chicken is allocated. After pressing the PLU key, the multiplication key and the value number key “2” are pressed. Thereby, the merchandise data for one canned beer pack and the merchandise data for two chickens are registered in the transaction buffer 51 of the RAM 23. The product data is data of a PLU number, a product code, a unit price, a sales point, and a sales amount. Since the product purchased by the customer is now complete, the store clerk presses the total key.

  Then, the PLU number registered in the transaction buffer 51 is searched for whether there is a PLU number set as a pack sales product in the set product parent-child master table 44. Since the PLU number 101 of the can beer pack is set as a pack sale product in the table 44, the can beer pack is searched as the pack sale product, and the PLU number 001 of the single can beer constituting the pack constitutes the pack. The number “6” and the unit price “230” are acquired.

  Then, it is searched whether there is a PLU number “1” of the canned beer alone in the set product table 43. Since the PLU number 001 is set as a set sale product in the table 43, the PLU number 010 and the PLU number 011 corresponding to the product sold as a set are subsequently acquired in the table 43. After that, it is searched whether the PLU number 010 and the PLU number 011 are in the transaction buffer 51 sequentially. Since the PLU number 010 is registered in the transaction buffer 51, it is determined that set sales have been established. Then, the discount amount “60” and the establishment score “1” are registered in the set establishment data area 52 of the RAM 23 corresponding to the M & M number 1001 of the set established with reference to the set discount table 42. Since the number of sales points corresponding to the PLU number of chicken is 2, another set of canned beer and chicken is established, and the number of points corresponding to the M & M number 1001 is “2”. Since the PLU number 011 is not registered in the transaction buffer 51, set sales are not established. Further, since the pack sales product sold as a pack other than the canned beer pack is not registered in the transaction buffer 51, the product sales registration process is subsequently performed. At that time, the transaction total amount and the discount total amount are calculated, and an amount “¥ 1620” obtained by subtracting the total discount amount from the transaction total amount is displayed on the display 13 with the touch panel and the display 14.

  After confirming the display on the display 14, the customer gives 2000 yen to the store clerk. After confirming the price displayed on the display 13 with the touch panel, the store clerk inputs a numerical value corresponding to 2000 yen delivered from the customer by using the numeric key and presses the deposit / cash key. Then, the change “¥ 380” is displayed on the display 13 with the touch panel and the display 14, a receipt is printed and issued, and the drawer 17 is opened. The clerk hands the change 380 taken out from the drawer 17 together with the printed receipt to the customer and closes the drawer 17.

  The customer confirms the change and confirms the handed receipt. FIG. 12 is a diagram showing a print display example of the receipt 61. As shown in the figure, “-¥ 120” 61a indicating the amount of money that is discounted when two sets of M & M number 1001 are established is printed, along with printed indications regarding canned beer packs and chicken that have been traded for merchandise. It is displayed. In addition, a message 61b indicating that a total of 120 yen has been reduced due to the completion of set sales is also printed.

  According to the POS terminal 1 of this embodiment, if there is a PLU number assigned to a pack sales product sold as a pack in one transaction, the single sales product constituting the pack and other registered singles It is automatically determined whether it is established as a set sale product with the PLU number assigned to the sale product, and when it is established as a set sale product, the discount amount set for that set is the value of the product registered as one transaction. It can be discounted from the total amount of transactions. Therefore, even if the PLU number given to the pack sale product and the PLU number given to the single sale product constituting the pack are different, if it is established as a set sale product, it is surely set to the set sale product. Discounts can be made so that customers can avoid complaints and the store clerk depresses the PLU key of a single sale product that makes up a pack sale product, and then multiplies the number of single sale products that make up that pack. It is not necessary to perform unnecessary operations, and it is not necessary to make the store clerk aware of such operations, so the burden on the store side can be reduced.
