In these, values input using the input unit 2 and processing results by the units 5, 6, 7, 8, 9, 13 and the like are stored.
Furthermore, the total consumption tax amount (value calculated by the consumption tax amount total calculation unit 10) and the difference amount (difference amount calculated by the difference amount calculation unit 12) are stored.

  The tax rate storage unit 4 stores the tax rate in association with the tax code, an example of which is shown in FIG. FIG. 6 is a diagram showing an example of the contents stored in the tax rate storage unit 4. In the example of FIG. 6, the tax rate “5”%, which is the current consumption tax rate, is stored for the tax code “V5”.

The tax-excluded / tax-included unit price calculation unit 5 uses the unit price A (j) excluding tax and the tax rate TAX (k) for each item for which the unit price excluding tax is input and the tax flag is 1, and rounds off the decimal part. The tax-included unit price B (j) is calculated, and the calculation result is stored in the corresponding part of the input / processing result storage unit 3 (the unit price including tax with the item number j).
B (j) = A (j) × {1 + TAX (k)}
However, j is an item number and k is a tax code of item number j. The same applies to other cases.
The unit price A (j) excluding tax is a value entered on the purchase request screen. The tax rate TAX (k) is the value of the tax rate stored in the tax rate storage unit 4 of the tax code input in the tax code input field 2i.

The tax-excluded / tax-included unit price calculation unit 5 uses the tax-included unit price B (j) and the tax rate TAX (k) for each item for which the tax-included unit price is input and the tax flag is not 1, and rounds off the decimal point. A (j) is calculated, and the calculation result is stored in the corresponding place (unit price without tax of the item number j) of the input / processing result storage unit 3.
A (j) = B (j) ÷ {1 + TAX (k)}
The tax-included unit price B (j) is a value entered on the purchase request screen. The tax rate TAX (k) is the value of the tax rate stored in the tax rate storage unit 4 of the tax code input in the tax code input field 2i.
The tax-excluded / tax-included unit price calculation unit 5 calculates the tax-included unit price for the tax-excluded unit price based on the tax rate and the tax-excluded unit price, and calculates the tax-excluded unit price for the tax-included unit price based on the tax rate and the tax-included unit price. (First calculation means).

For example, when input is made as shown in FIG. 2, the tax-excluded / tax-included unit price calculation unit 5 performs the following calculation.
B (10) = 200 × (1 + 0.05) = 210
B (20) = 150 × (1 + 0.05) = 157
B (30) = 150 × (1 + 0.05) = 157

The tax unit price calculation unit 6 uses the tax-excluded unit price A (j) and the tax rate TAX (k) for each detail, calculates the tax unit price C (j) by rounding off the decimal point, and inputs and processes the calculation result. Stored in the corresponding part (the tax unit price of the item number j) of the result storage unit 3.
C (j) = A (j) × TAX (k)
However, the value stored in the input / process result storage unit 3 is used for the tax-excluded unit price A (j). In other words, the tax-excluded unit price A (j) is the value entered on the purchase request screen for items for which the tax-excluded unit price is entered and the tax flag is 1, and for items for which the tax-included unit price is entered and the tax flag is not 1. This is the value calculated by the extraction / tax-included unit price calculation unit 5. The tax rate TAX (k) is a value of the tax rate stored in the tax rate storage unit 4 of the tax code input in the tax code input field 2i.

For example, when input is made as shown in FIG. 2, the tax unit price calculation unit 6 performs the following calculation.
C (10) = 200 × 0.05 = 10
C (20) = 150 × 0.05 = 7
C (30) = 150 × 0.05 = 7

The tax-excluding total calculation unit 7 calculates the tax-excluded amount E (j) using the unit price A (j), the purchase quantity D (j), and the unit for each item. Subsequently, the tax-excluding total calculation unit 7 sums the calculated tax-excluded amounts E (j) of the respective details to calculate the tax-excluding total Etotal (= E (10) + E (20) +... + E (max): max is The number of the lowest detail) is calculated. Then, the tax-excluding total calculation unit 7 stores the calculation result in a corresponding part (tax-excluding total) of the input / processing result storage unit 3. For example, when the unit is entered as “CS (case)”, the purchase amount D (j) is converted into the purchase amount with “PC (piece)” as the unit, and the tax-excluded amount is calculated. The That is, the tax-excluded amount E (j) is calculated by multiplying the tax-excluded unit price A (j) by the purchase quantity after the unit is converted to “PC (piece)”.
However, the value stored in the input / process result storage unit 3 is used for the tax-excluded unit price A (j). In other words, the tax-excluded unit price A (j) is the value entered on the purchase request screen for items for which the tax-excluded unit price is entered and the tax flag is 1, and for items for which the tax-included unit price is entered and the tax flag is not 1. This is the value calculated by the extraction / tax-included unit price calculation unit 5.

For example, when the input is made as shown in FIG. 2, the tax-excluding total calculation unit 7 performs the following calculation.
E (10) = A (10) × D (10) = 200 × 10 = 2000
E (20) = A (20) × D (20) = 150 × 9 = 1350
E (30) = A (30) × D (30) = 150 × 1 = 150
Etotal = E (10) + E (20) + E (30)
= 2000 + 1350 + 150 = 3500

The consumption tax total calculation unit 8 calculates the consumption tax total Ftotal by using the total tax-excluded Etotal and the tax rate TAX, rounded down to the nearest decimal point, and inputs the calculation result in the corresponding part of the processing result storage unit 3 (total consumption tax ).
Ftotal = Etotal × TAX
However, a value stored in the input / processing result storage unit 3, that is, a value calculated by the tax-excluding total calculation unit 7 is used as the tax-excluding total Etotal. Further, the tax rate TAX is the value of the tax rate stored in the tax rate storage unit 4 of the tax code input in the specification because the same tax code is input in the present embodiment.
The above-mentioned tax-excluding total calculating unit 7 and consumption tax total calculating unit 8 calculate the total amount of tax for one slip based on the tax rate, the purchase quantity of each item and the unit price before tax (third). Calculation means).

For example, when input is made as shown in FIG. 2, the consumption tax total calculation unit 8 performs the following calculation.
Ftotal = 3500 × 0.05 = 175

The tax-included total calculation unit 9 uses the tax-excluded total Etotal and the tax rate TAX, calculates the tax-included total Gtotal by rounding down the decimal part, and stores the calculation result in the corresponding part (tax-included total) of the input / processing result storage unit 3 To do.
Gtotal = Etotal × (1 + TAX)
However, a value stored in the input / processing result storage unit 3, that is, a value calculated by the tax-excluding total calculation unit 7 is used as the tax-excluding total Etotal. Further, the tax rate TAX is the value of the tax rate stored in the tax rate storage unit 4 of the tax code input in the specification because the same tax code is input in the present embodiment.
Note that the above-mentioned tax-excluding total calculation unit 7 and tax-included total calculating unit 9 calculate the tax-included total for one slip based on the tax rate, the purchase quantity of each item and the unit price excluding tax (second calculation). means).

For example, when input is made as shown in FIG. 2, the tax-included total calculation unit 9 performs the following calculation.
Gtotal = 3500 × (1 + 0.05) = 3675

The total consumption tax amount calculation unit 10 calculates the consumption tax amount H (j) using the tax unit price C (j), the purchase quantity D (j), and the unit for each detail. Subsequently, the total consumption tax amount calculation unit 18 adds up the calculated consumption tax amounts H (j) of the respective details to calculate the total consumption tax amount Htotal (= H (10) + H (20) +... + H (max): max is the number of the lowest detail). And the consumption tax amount total calculation part 10 stores a calculation result in the applicable location (total consumption tax amount) of the input / process result storage part 3. However, for example, when the unit is entered as “CS (case)”, the purchase quantity D (j) is converted into the purchase quantity with “PC (piece)” as the unit, and the total consumption tax amount is calculated. To do. That is, the consumption tax amount H (j) is calculated by multiplying the tax unit price C (j) by the purchase quantity after the unit is converted to “PC (piece)”.
However, the value stored in the input / process result storage unit 3, that is, the value calculated by the tax unit price calculation unit 6 is used as the tax unit price C (j).
The above-described tax unit price calculation unit 6 and the consumption tax amount total calculation unit 10 calculate the consumption tax amount for each item based on the tax rate, the unit price before tax, and the purchase quantity, and the consumption tax for each item calculated. The total amount of consumption tax is calculated by summing the amounts (fourth calculation means).

For example, when input is made as shown in FIG. 2, the consumption tax amount total calculation unit 10 performs the following calculation.
H (10) = C (10) × D (10) = 10 × 10 = 100
H (20) = C (20) × D (20) = 7 × 9 = 63
H (30) = C (30) × D (30) = 7 × 1 = 7
Htotal = H (10) + H (20) + H (30)
= 100 + 63 + 7 = 170

  The total tax amount comparison unit 11 refers to the storage contents stored in the input / process result storage unit 3 and includes the total consumption tax Ftotal (value calculated by the total consumption tax calculation unit 8) and the total consumption tax amount Htotal ( And the value calculated by the consumption tax amount total calculation unit 10).

The difference amount allocation unit 13 adds the difference amount DIFF (value calculated by the difference amount calculation unit 12) to the tax-included unit price B (max) and the tax unit price C (max) of the lowest item, The tax-included unit price B (max) and the tax unit price C (max) of the lower details are updated. Then, the difference amount allocation unit 13 stores the update result in the corresponding part (the tax-included unit price and the tax unit price of the item number max) of the input / process result storage unit 3.
B (max) = B (max) + DIFF
C (max) = C (max) + DIFF
However, the values stored in the input / processing result storage unit 3 are used as the difference amount DIFF, the tax-included unit price B (max), and the tax-included unit price C (max).
In addition, the tax-excluded unit price of each item is calculated by the above-described total tax-excluding calculation unit 7, the total consumption tax calculation unit 8, the total consumption tax amount calculation unit 10, the difference calculation unit 12, and the difference distribution unit 13. The tax-included unit price is adjusted so that the tax-included unit price based on the purchase quantity matches the tax-included unit price per slip (adjustment means).

For example, when the input is made as shown in FIG. 2, the difference amount allocation unit 13 performs the following calculation.
B (30) = B (30) + DIFF = 157 + 5 = 162
C (30) = C (30) + DIFF = 7 + 5 = 12.

The purchase requester can easily make a purchase request at a unit price including tax.
Moreover, since it is necessary to input so that the purchase quantity of the lowest-order item becomes 1, it is possible to prevent a situation in which a fraction is generated again when distributing the difference amount. Further, since the purchase quantity of the lowest order item is set to 1, it is not necessary to search for the item having the purchase quantity of 1, thereby reducing the load on the purchase request support apparatus 1.

Although the preferred embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various design changes can be made within the scope described in the claims. is there.
For example, when the purchase request screen is displayed, a message is displayed to inform the purchase requester that the purchase quantity of the lowest item is input to be 1 PC (piece), or purchase When the requester inputs the purchase quantity of the lowest item other than 1PC (piece), a message is displayed to inform that the purchase quantity of the lowest item must be entered to be 1PC (piece). You may comprise as follows.
In the above embodiment, the purchase quantity of the lowest specification must be input as 1 PC (piece). However, the present invention is not limited to this. For example, the purchase quantity of at least one specification may be input as 1 PC (piece), and the details of the adjustment destination of the difference amount may be determined according to a predetermined procedure. As a predetermined procedure, for example, the purchase quantity is confirmed in order from the highest level item (the item with the smallest item number) or from the lowest level item, and the purchase quantity is confirmed to be 1 PC (piece) for the first time. Is a procedure that uses as the adjustment destination.
Furthermore, in the above-described embodiment, either the tax-excluded unit price or the tax-included unit price may be input. However, the present invention is not limited thereto, and only the tax-excluded unit price may be input. . In this case, the tax-excluded / tax-included unit price calculation unit 5 only needs to be able to calculate only the unit price including tax from the unit price excluding tax, and the unit price excluding tax used by each unit 5, 6, 7, 10, etc. is the value input by the input unit 2. It becomes.

Moreover, in the said embodiment, although it is a case where the same tax code is input with respect to each specification, you may comprise so that the input of a different tax code is not restricted to this.
In this case, the consumption tax total calculation unit 8 searches for the details of the same tax code from the input details, and the tax-excluded amount E (j) calculated by the tax-excluding total calculation unit 7 for each item of the same tax code. Are totaled, and a total tax-exclusive Etotal (i) relating to the same tax code is calculated. This is done for each tax code. i indicates a tax code. The consumption tax total calculation unit 8 multiplies the tax-excluded total Etotal (i) by the tax rate TAX (i) of the tax code for each tax code, rounds down the decimal point, and totals the consumption tax Ftotal (i) (= Etotal (i) × TAX (i)) is calculated and summed to calculate the total consumption tax Ftotal.
For example, “the purchase quantity of the item number 10 is 1 PC (piece), the unit price before tax is 100, the tax code is V5 (5%)”, “the purchase quantity of the item number 20 is 2 PC (piece), the unit price before tax is 200, "Tax code is V0 (0%)", "Purchase quantity of item number 30 is 3PC (piece), Unit price before tax is 300, Tax code is V3 (3%)", "Purchase quantity of item number 40 is 4PC (piece) ), Unit price before tax is 400, and tax code is V5 (5%).
Ftotal (V5) = Etotal (V5) × TAX (V5)
= (100 × 1 + 400 × 4) × 0.05 = 85
Ftotal (V3) = Etotal (V3) × TAX (V3)
= (300 × 3) × 0.03 = 27
Ftotal (V0) = Etotal (V0) × TAX (V0)
= (200 × 2) × 0.00 = 0
Ftotal
= Ftotal (V5) + Ftotal (V3) + Ftotal (V0)
= 85 + 27 + 0 = 112
The tax-included total calculation unit 9 searches for the details of the same tax code from the entered details, and sums the tax-excluded amount E (j) calculated by the tax-exclusive total calculation unit 7 of each detail of the same tax code. Then, the tax-excluding total Etotal (i) for the same tax code is calculated. This is done for each tax code. i indicates a tax code. The tax-included total calculation unit 9 uses the tax-excluded total Etotal (i) and the tax rate TAX (i) of the tax code for each tax code, rounds off the decimal point, and includes the tax-included total Gtotal (i) (= Etotal (I) × {1 + TAX (i)}) is calculated, and these are added together to calculate the tax-included total Gtotal.
For example, “the purchase quantity of the item number 10 is 1 PC (piece), the unit price before tax is 100, the tax code is V5 (5%)”, “the purchase quantity of the item number 20 is 2 PC (piece), the unit price before tax is 200, "Tax code is V0 (0%)", "Purchase quantity of item number 30 is 3PC (piece), Unit price before tax is 300, Tax code is V3 (3%)", "Purchase quantity of item number 40 is 4PC (piece) ), Unit price before tax is 400, and tax code is V5 (5%).
Gtotal (V5) = Etotal (V5) × {1 + TAX (V5)}
= (100 × 1 + 400 × 4) × (1 + 0.05) = 1785
Gtotal (V3) = Etotal (V3) × {1 + TAX (V3)}
= (300 × 3) × (1 + 0.03) = 927
Gtotal (V0) = Etotal (V0) × {1 + TAX (V0)}
= (200 × 2) × (1 + 0.00) = 400
Gtotal
= Gtotal (V5) + Gtotal (V3) + Gtotal (V0)
= 1785 + 927 + 400 = 3112
