France Tax User Defined Function

The FRANCE_TAX.FUN user defined function allows you to handle the special situation where different tax percentages are applied to an element depending on whether it is posted as part of a package, or "manually" as a separate item. Using this function, you can, for example, charge a 5% tax on a dinner if it is consumed against a package, and 7% in all other cases. The following example shows how to use the FRANCE_TAX function.

Create a package code called DINNER (System Configuration>Rate Management>Packages>Codes) having a package type of Element.

Assign transaction code 5000 to the package (Code field in Transaction Details block).
Do not select the Tax Inclusive check box.
Select the Allowance check box.
Do not select Post Next Day.
On the Package Details tab, set the Price to 20. Set Allowance to 20.

Edit transaction code 5000 (System Configuration>Cashiering>Codes>Transaction Codes).

On the Transaction Code Edit screen, make sure the Generates Inclusive check box is not selected.
Select the Generates button.
Attach the tax transaction code using the Generates Edit screen.
Select the UDF Function option button and enter FRANCE_TAX(5,7) in the text entry area. This will be interpreted by OPERA to mean you want to apply a 5% tax when the charge is posted against the package, and 7% when posting manually (or when posting a package overage).
Note: If you have specified an overage transaction code on the package element, you must also attach this same generates configuration to that transaction code as well.
