Inbound processing of INVOIC IDOC without PO number and item check

Question

Hi All,
I'm processing an Inbound INVOIC IDOC to create an Intercompany Vendor Invoice against a Purchase order but wish to do process this based on the delivery note number rather than the PO number. The INVOIC IDOC will not contain a reference to the Purchase order and thus the need to process it based on the delivery note number which will be referenced in the Purchase order Goods receipt.
However, when processing the Inbound INVOIC IDOC it is validating that the number in IDOC segment E1EDP02 with QUALF 001 is the purchase order number. In this scenario it won't be and therefore it errors. The delivery note number is in IDOC segment E1EDP02 with QUALF 016.
Could someone please tell me if there is a standard way that we can have this Inbound INVOIC IDOC processing using only the delivery note?. If I manual process in the MIRO transaction I can process an Invoice based on the dleivery note in the Goods receipt so would expect I should be able to do so also with the IDOC processing.
I have noticed that IDOC segment E1EDP19 with QUALF 003 is not being populated and therefore according to the SAP help the IDOC segment E1EDP19 with QUALF 002 holding the Vendor material number is checked. Could this have something to do with it not being able to process the Invoice using only the delivery note number reference?.
Thanks in advance,
Michael

Hi Karen,
According to Note 103051 - EDI: Multiple reference to same purchase order item.
Module IDOC_INPUT_INVOIC_MRM (only as of Release 4.0) for the logistics invoice verification can distinguish different goods receipts by means of the delivery note number. For this purpose, GR-related invoice verification must be active. Please check the note.
Thank you,
