SAP Business ByDesign

1. Go to Supplier Invoicing work center.
2. Go to Invoices and Credit Memos view.
3. Open supplier invoice ABC. (ABC represents the affected supplier invoice ID)
4. You see below errors on the supplier invoice:
   • The item does not have a reference to a purchase order. Go to the exception and check whether the item should have a reference to one of the proposed documents.
   • Account assignment data missing for item X; see Cost Distribution
5. And this supplier invoice is created from customer invoice, even there is no purchase order and inbound delivery created in this process.

Although you create sales order only, however the seller and the account are partner company, which means you maintain the internal EDX as output channel in both account and supplier master for Customer Invoice / Credit Memo and Purchase Oder.

This will create the supplier invoice from customer invoice since supplier invoices only consider the output of customer invoice in intercompany scenario, regardless of whether there is purchase order or not. 

This is expected behavior.

You can void the supplier invoice manually if not needed.
