SAP Note 23464 - Transfer corrections with function modules

Symptom:

When creating new function modules in an existing function group (Z...), the entire function group (Z...) is entered automatically as an object into the correction. The individual module (LZ...U.) is only entered when changing existing modules.
When creating a new function module, is it possible to only transport this module and not the complete group?.

Solution
When creating a function module in an existing function group, the complete function group must be transported so that the consistency of the entire group is preserved.
Not only is the include LggggUnn created, but a change is also made in the include LggggUXX, and table entries for the tables TFDIR and TFTIT are created.
