I have some problem during Purch. Order creation.
In our SAP the G/L Account and Commitment Item (FM) linked with Material group, so when i create PO for services and enter the Material group,-> is defined the Commitment Item in Account Assignment, and combination of "Acc. Ass. Category" + "Material group" is defined the G/L Account... ->so, PO is created. BUT if somebody need to change the Material group -> G/L Account and Commitment Item do not updated!! and follow-up process with this PO, be displayed in the budget is incorrect..!
why the information is not updated automatically?
p.s if i go to Account Assignment of service in Line 10 and enter to button "Continue (Enter)" the Commitment Item updated, but G/L account remained the same.(do not updated)
