3791646 - Account Assignment Category not mandatory in PR for valuated materials - SAP ERP & SAP S/4HANA

• When creating a Purchase Requisition in the Manage Purchase Requisitions Fiori app or transaction ME51N, the Account Assignment Category field is not enforced as mandatory for certain materials.

• Saving or submitting the PR without populating Account Assignment data does not trigger error message 06 026; the PR proceeds to active status without a hard stop.

• The behavior differs between materials even when their material type configuration appears similar. For some materials the error triggers correctly; for others it does not.
