In O2C process, when i do the goods issue for a delivery, Accounting Document is being created properly but the Additional Account Assignment fields in accounting doc are not being populated. Fields missing are Cost Center, WBS Element, Sales Order, Material etc. These are visible in the material document but not being populated in the Accounting document. Are there any specific copy controls for Accounting document other than the SD Copy controls. I believe SD Copy controls are only to populate the material docs such as delivery, billing etc. I checked the OMJJ, OKB9, Substitutions but everything seems to be in place.
How are these fields controlled and populated?
