In MM and XI, invoice items with PO reference can be proposed in the Accounting Block. If this results in duplicates with existing account assignments for lines, an error message would be output.

Two line items are treated as duplicates when the purchase-order number (EBELN), the PO item (EBELP), the goods receipt number (LFBNR), the goods receipt line item (LFPOS), and the fiscal year of the goods receipt (LFGJA) are identical, which would prevent later posting or parking of the document.

In some situations, the output of an error message such as this will prevent additional line items that are actually valid from being generated, as in the following case:

A goods receipt has already been posted for a PO line item with goods-receipt invoice verification, and the user generated a proposal for this PO line item in the Accounting Block. Now a second goods receipt is generated for this line item without a delivery note number having been entered. If you now attempt to initiate a line-item proposal in the xFlow Accounting Block again, then an error message will appear due to duplicates. The reason is that both goods receipt will be proposed and the first is already present in the account-assignment block.

In the current version, on the other hand, only an informational message will be output. The new proposal of the first goods receipt will be ignored and the proposal for the second goods receipt will be added to the account-assignment block.

Example

A purchase order with GR-related invoice approval and a posted goods receipt:

In the XI workflow in the task "Check Goods Receipt", an invoice line item will be proposed for this PO item.

If another goods receipt was now entered and the PO item proposed again, the error notification mentioned would be output. In the current version, on the other hand, an additional line item is generated:
