I'm trying to implement mandatory check of TU assignment during GR processing. If DTU not equal 9, error message should appear. Is there any standard solution, like incompletnes check, to have it working properly or BADI implementetion would be necessary? If BADI, then which one? Was not able to find the correct one in GR processing. I could do it quite easily one step later in packing dialogue but it would be for me little bit too late. (reversal GR would be necessary).
Any hints are welcome 😊
