Image/data in this KBA is from SAP internal systems, sample data, or demo systems. Any resemblance to real data is purely coincidental.

SAP S/4HANA Cloud Public Edition

1. Create a supplier invoice in MIRO.
2. Select "Supplier" in the PO Reference tab and enter a supplier.
3. Press enter, message "PO supplier is not an invoicing party. Enter the invoicing party" is issued.
   

The message occurs because the supplier does not have master data maintained for the relevant company code.

When creating supplier invoice with reference to Supplier, system determined the invoicing party based on below logic:
Firstly system uses the supplier as criterial to select purchase orders. Then if the invoicing party field in the first purchase order (EKKO-LIFRE) has value, the supplier invoice (P_RBKPV-LIFNR) uses this field as invoicing party. Otherwise the supplier invoice uses supplier field in purchase order (EKKO-LIFNR) as invoicing party.

There are two options to resolve this issue:

• Maintain master data for the supplier in the relevant company code.
• Alternatively, update the purchase order to include an invoicing party in the "Partner Function" tab and ensure that the invoicing party in the purchase order has master data maintained for the relevant company code.
