Hi Hakan,
1 - We implemented only the PREPARE method of ORDER_SAVE BAdI. The other methods (CHANGE_BEFORE_UPDATE, CHECK_BEFORE_SAVE) are empty and we only have this one implementation of ORDER_SAVE.
Do you think moving the code from PREPARE to CHANGE_BEFORE_UPDATE will solve this issue? I will move the coding to CHANGE_BEFORE_UPDATE method in our development system. Unfortunately I think I will only be able to test it in January.
Best regards
Sascha
