The Development system is working fine after implementing one SAP note then moving to the Quality system shows that the function group contains errors.
The function module 'FIWTIN_UPDATE_ACCUMULATION' (created by Notes) is there at Qas but Include LJ1IEWTU25 has not been included in its function group's include program at Qas, which means not registered.

- To open the repair tool, on the initial screen of the Function Builder, choose Utilities -> Repair function group.


Here need extra access to execute the repair operation as it's re-generated standard function group.
