I have a question.
We created S/O with field "Material Group 1" empty (Additional data A, field VBAP-MVGR1).
Then we changed the SW/O item and fill in "Material Group 1" field (Via VA02).
We customized table TKEZU: WWXXX KEDR KOMP-MVGR1.
Now, when we create the billing document the characteristic WWXXX was empty.
Also, when I tried to make KE4S/KE4ST it doesn't reflected in the new derivation.
Please your Advise.
