And the display control part 12 displays the merchandise information edit screen 42 with respect to the clicked goods on the liquid crystal display 40, as shown in FIG.

  FIG. 6 is a diagram illustrating an example of the product information editing screen 42. As shown in FIG. 6, the product information editing screen 42 displays the product name of the selected product, a comment related to the product, a normal price, and a sales price. Further, the product information editing screen 42 displays the lowest price for reference when the operator edits the sales price. The product information editing screen 42 is provided with a frame for accepting text input for items that can be changed, such as product names, comments, and sales prices, as shown in FIG. The product information editing screen 42 is provided with a “confirm” button for confirming the accepted input.

  The input receiving unit 13 functions as an input receiving unit. The input receiving unit 13 receives inputs such as a sales price, a product name, and a comment regarding the product input from the product information editing screen 42. The operator inputs product information to be changed from the product information editing screen 42 by operating the keyboard 25 and the mouse 26, and edits the product information by clicking the “Confirm” button to confirm the input.

  The price determination unit 14 functions as a determination unit, and determines whether or not the sales price received by the input reception unit 13 in the product information editing screen 42 is within the price range, that is, whether or not the minimum price is exceeded.

  The error display unit 16 functions as a notification unit. If the price determination unit 14 determines that the sales price of the product input on the product information editing screen 42 is out of the price range, that is, the price is lower than the minimum price, the error display unit 16 displays the liquid crystal display 40. The error display screen 43 shown in FIG. Accordingly, the error display unit 16 notifies the operator that the sales price of the input product is outside the set price range.

  FIG. 7 is a diagram illustrating an example of an error display screen 43 displayed as a pop-up on the liquid crystal display 40. As shown in FIG. 7, the error display screen 43 displays a warning message such as “The entered selling price is below the minimum price. Please re-enter the selling price of 80 yen or more”. After confirming the warning message, the operator clicks the “re-enter” button to return to the product information editing screen 42 shown in FIG. 6 and re-enter the sales price.

  In addition, the error display screen 43 displays a message “Please enter your passcode when canceling the minimum price restriction”. The operator inputs a passcode in the input field provided in the lower right part of the error display screen 43 and clicks the “OK” button. As a result, the operator can close the error display screen 43 to cancel the error warning and set a selling price lower than the minimum price.

  The information registration unit 15 functions as information registration means. When the price determination unit 14 determines that the sales price of the product input on the product information editing screen 42 is within the price range, that is, is equal to or higher than the minimum price, the information registration unit 15 inputs the sales price. Is stored in the product table 31 as a sales price for the product code of the product.

  In addition, even if the price determination unit 14 determines that the selling price is lower than the minimum price, the information registration unit 215 edits the product information when the passcode input reception unit 17 authenticates the passcode. The sales price input on the screen 42 is stored in the product table 31, and the sales price is updated.

  Next, the procedure of the product information editing process performed by the sales management server 2 will be described. FIG. 8 is a flowchart showing the procedure of product information editing processing performed by the sales management server 2.

  First, the display control unit 12 displays the product information list screen 41 (see FIG. 5) on the liquid crystal display 40 (step S1). The display control unit 12 determines whether or not the “edit” button has been clicked (step S2). When the “edit” button is not clicked (step S2: No), input is waited until it is clicked (step S2). When the “edit” button is clicked (step S2: Yes), the display control unit 12 displays the product information editing screen 42 shown in FIG. 6 (step S3).

  The input receiving unit 13 determines whether or not the “confirm” button is clicked on the product information editing screen 42 (step S4). If the “confirm” button is not clicked (step S4: No), input is waited until it is clicked (step S4). When the “confirm” button is clicked (step S4: Yes), the information registration unit 15 determines whether or not the sales price has been changed (step S5). If there is a change in the sales price (step S5: Yes), the price determination unit 14 determines whether or not the input sales price is equal to or higher than the minimum price with reference to the product table 31 (step S6). On the other hand, if there is no change in the selling price (step S5: No), the process proceeds to step S7.

  In step S6, when the price determination unit 14 determines that the sales price is equal to or higher than the minimum price (step S6: Yes), the process proceeds to step S7. In step S <b> 7, the information registration unit 15 stores the sales price input on the product information editing screen 42 and other input product information in the product table 31 and ends the process.

  On the other hand, when the price determination unit 14 determines in step S6 that a selling price lower than the minimum price has been input (step S6: No), the error display unit 16 pops up an error display screen 43 (see FIG. 7). (Step S8). Then, the error display unit 16 determines whether or not the “re-input” button is clicked by the operator (step S9). When the “re-input” button is clicked, the process proceeds to step S3, and the processes after step S3 are performed as described above.

  On the other hand, when the “re-input” button has not been clicked (step S9: No), the passcode input reception unit 17 determines whether or not the “OK” button has been clicked (step S10). If the “OK” button is not clicked (step S10: No), input is waited until it is clicked (step S10). When the “OK” button is clicked (step S10: Yes), the passcode input receiving unit 17 determines whether or not the passcode is authenticated (step S11). When the passcode is authenticated (step S11: Yes), the information registration unit 15 stores the input sales price in the product table 41 (step S7). When the passcode is not authenticated (step S11: No), the passcode input reception unit 11 pops up an error message such as “Passcode could not be authenticated” (step S12), and then returns to step S8. Then, the process of step S8 is continued.

  As described above, in the sales management server 2 according to the present embodiment, the sales price of the product input on the product information editing screen 42 is lower than the lowest price of the product stored in the product table 31. When the price determination unit 14 determines, an error display screen 43 is displayed by the error display unit 16. As a result, the operator can recognize that the sales price has been input by mistake, and an erroneous setting of the sales price can be prevented.

  In addition, as described above, the sales management server 2 according to the present embodiment can update the sales price by inputting the passcode even when the sales price is outside the predetermined price range. . Accordingly, a sales price outside the price setting range can be set at a special sale such as a stock disposal sale.

  Further, as shown in FIG. 7, the error display unit 16 clearly indicates a minimum price such as “Please re-enter a sales price of 80 yen or more” on the error display screen 43, so the operator can correct the sales price. Can be performed more smoothly.

  In the above description, when it is determined that the sales price input on the product information editing screen 42 is lower than the minimum price of the product stored in the product table 31, an error display screen 43 is displayed in a pop-up manner. However, a warning may be displayed in other cases. For example, the price determination unit 14 determines whether the input sales price is lower than the normal price stored in the product table 31. When a price lower than the normal price is input, the error display unit 16 may display an alert display screen 44 as shown in FIG. 9 on the liquid crystal display 40. As a result, the operator confirms that the product is discounted one by one, and the discount processing can be performed carefully.

  In addition, when setting a price range in the product table 31, the price range for each product may be input and set one by one, or a predetermined percentage of the normal price is discounted or increased for a plurality of products. You may set prices all at once. As an example of the latter, it is possible to collectively set half the normal price of each product as the lowest price. In this way, when setting the price range of each product in the product table 31, it is possible to input the price range of a plurality of products at once without manually entering each product. Has the advantage of saving labor.

(Second Embodiment)
Next, a second embodiment of the present invention will be described. In the present embodiment, even when a plurality of identical products are sold together as a set, the unit price per product is calculated and it is determined whether or not the calculated unit price is within the price range.

  FIG. 10 is a block diagram illustrating a hardware configuration of the sales management server 202 according to the second embodiment. The same components as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted here. As shown in FIG. 10, the HDD 30 of the sales management server 202 stores a product table 231 that is different from that of the first embodiment.

  FIG. 11 is a schematic diagram illustrating an example of the product table 231. As shown in FIG. 11, in addition to the product table 31 of the first embodiment, the product table 231 further stores the number of sets (the number of products) when a product is sold as a set. The product table 231 stores a price range per product as a product price range.

  As shown in FIG. 11, for example, for a product of product code 00003 “tea 500 ml × 24 (set sale)”, there are 24 plastic bottles per set, so the number of sets is set to 24 In addition, the price range per product is set at 80 yen, which is the lowest price per 500 ml plastic bottle.

  As an advantage of setting the price range per product in this way, it is easy to compare the price range per product, so the price range per product is the same price for single product sales and set sales. It becomes easy to do.

  As another advantage, the price range per product can be made the same for both single item sales and set sales. That is, in FIG. 11, when 500 ml of tea with a product code of 000001 and 500 ml of 24 tea with a product code of 000003 are compared at a unit price per unit with a minimum price of 80 yen per unit. Can have the same minimum price.

  As a specific example, when a product search is performed as “Drink> Tea> Tea (500 ml)” in the product category on the product information list screen 41 (see FIG. 5), tea in a 500 ml plastic bottle is the manufacturer. It is extracted regardless of single item sales or set sales. If the minimum price per item is set to 80 yen for all products in the search results, the price range of similar products can be set uniformly, and the setting operation can be performed efficiently. .

  The display control unit 212 displays the product information editing screen 242 on the liquid crystal display 40 based on the product information stored in the product table 231 (step S23).

  In step S5 of FIG. 14, when the selling price is changed (step S5: Yes), the process proceeds to step S20. The price determination unit 214 calculates the sales price per product by dividing the input sales price by the number of sets stored in the product table 231 (step S20). When the number of sets is changed on the product information editing screen 242, the price determination unit 214 calculates the sales price per product by dividing the sales price of the product by the set number of input ( Step S20).

  Next, the price determining unit 214 refers to the product table 231 and determines whether or not the selling price per piece calculated in step S20 is equal to or higher than the minimum price (step S26). When it is determined that the sales price per piece is equal to or higher than the minimum price (step S26: Yes), the information registration unit 15 stores the sales price and other product information input on the product information editing screen 242 in the product table. It stores in H.231 (step S7). On the other hand, when the selling price per piece is less than the minimum price (step S26: No), the error display unit 16 pops up the error display screen 43 (step S8).

  As described above, the sales management server 202 according to the present embodiment can efficiently set the price range of similar products when setting the price range in the product table 231 and is required for the price range setting operation. There is an effect that the time can be shortened.
