Diagnosis
There are two possible causes.
The first is that some of the movement types in the document areconfigured so that the system automatically makes a posting to FI andthe system generates an open vendor item. Others are configured so thatno open items are generated. This mix prevents the system from creatingm an open item.
Alternatively, perhaps all of the movement types are configured so thatthey automatically generate an document, but they generate differenttypes of documents (for example, one generates an invoice and anothergenerates a credit memo).

Procedure
Use line items that have the same Customizing settings in tableJ_1BIMFI.
If the material document has been generated, you must post the FIdocument for the vendor manually.
