When creating a Purchase Requisition, it is possible to default a GL account based on Material group.
This is set in configuration:
IMG: MM > Purchasing > Material master > Entry Aids for Items without an material master
The GL account itself is link to the Valuation class in T030 (tcode omwb)
If the Entry Aids (default valuation class per material group) are not found, one can also set a default GL account in T030 by leaving the Valuation class blank. (First row in above example).
