Adjusting Function Modules (SAP Library - Changing the SAP Standard (BC))

Adjusting Function Modules

The system automatically adopts the following at release upgrade:

Modules created by customers
Parameters added by customers, as long as they do not conflict with any existing parameters
Process types that have modified by customers, as long as they are compatible with their modules’ parameters

The system offers you support during the adjustment process if:

A new parameter in the original has the same name as a modified parameter
The reference type of a parameter has changed in the original

The customer can choose pushbuttons in a dialog box to determine if the modifications are to be adopted or not.

If changes to the contents of an original function module are not compatible with a customer’s modifications, see the section on Modifications in Programs.

If problems still exist after adjustments have been made, a dialog box appears asking you to refer to the adjustment log for additional information. Unresolved problems can occur during process type modification if, for example, a function module is designated as "updateable" and export parameters have to be deleted.
