This documentation is copyright by SAP AG.

In this IMG activity, you create the function modules you want to use as check functions in input validations.

For the system to be able to perform input validation correctly in the PI sheet, bear the following in mind:

• Input validation may be carried out several times in the PI sheet. For this reason, the function module must be programmed in such a way that it can be called repeatedly and several times.

• The function module must return an exception for invalid input values. The corresponding system messages is displayed as a warning in the PI sheet.

If the function module does not return an exception, the input value is regarded as valid in the PI sheet.

Create the required function modules in the customer namespace.

Caution:

Customer data that is not within the customer namespace is overwritten in release upgrades. For this reason, use names that begin with the following characters:

• Function groups, with Y or Z

• Function modules, with Y_ or Z_

For general information on function module processing, refer to Application Help.
