# NON PO invoice posted as proxy from AN

## Resolution

**Issue**

NON PO Invoice is posted from AN to SAP via Managed Gateway for Spend&Network and the invoice post as IDOC in ERP instead of PROXY.

**Resolution**

In Managed Gateway for Spend&Network cross ref parameter - maintain InvoiceProcessingType as 'FI' for doc type 'InvoiceDetailRequest' . This should convert NONPO as proxy in Managed Gateway for Spend&Network outbound payload .

**Additional Information**

From SAP Integration Suite, managed gateway for spend management and SAP Business Network, the FI-invoice or FI credit memo of the document type FIInvoiceDetailRequest corresponding to the non-PO invoice or non-PO credit memo from SAP Business Network is passed on to the buyer’s SAP ERP using the inbound proxy FI Invoice ERP Request (with the technical name InvoiceERPRequest\_In).
