I am currently trying to update the KNA1 by posting the IDOC DEBMAS06 with Data Services. The IDOC is posted succesfully and the status says "changes have been made". Also when checking the IDOC in WE19, I can see that I passed the intended data.
Nevertheless the record in KNA1 isnt updated and shows still the initial data. With the same IDOC I am also creating new datasets in the KNVV and KNVI, they on the other hand, get populated just as desired.
Looking forward to any suggestions on how to solve this.
