- PO &1 rejected: multiple use ?SAP Error Message:
WG449 PO &1 rejected: multiple use
Meaning / Cause:
This error occurs when a Purchase Order (PO) number is being used multiple times in a context where it is expected to be unique. Typically, this happens during Goods Receipt (GR) or Invoice Verification processes where the system detects that the PO number has already been referenced or processed, and the current transaction attempts to reuse it in a way that is not allowed.
Common scenarios include:
Check the PO usage:
Verify if the PO number &1 (the actual PO number will be shown in the message) has already been used in the current process or document. For example, check if a goods receipt or invoice referencing this PO has already been posted.
Check document references:
Ensure that the PO number is not being duplicated in the same document or across documents where uniqueness is required.
Review the process:
Check configuration:
Sometimes, this error can be related to settings in the system that control document number ranges or reference checks. Review the relevant configuration in Materials Management (MM) or Invoice Verification.
Master data check:
Verify the PO master data for correctness and consistency.
