SAP Error Message - Details

• Message type: E = Error

• Message class: M8 - Invoice Verification/Valuation

• Message number: 321

• Message text: Posición de pedido repetida en documento

¿Qué causa este problema?

If the following conditions are fulfilled, you can settle an order item
in an invoice received via EDI/SOA more than once:
Goods-receipt-based invoice verification has been defined for the order
item.
The delivery note numbers of the goods receipts are contained in the
IDoc or in the SOA message.

You are using differential invoicing and one previous invoice already
exists (as of second invoice). In other words, for each goods receipt
item or purchase order item, the system displays both the current item
(invoice item) and the item from the previous invoice document (credit
memo item) in accordance with the
<DS:GLOS.4F64D5AEFB615077E10000000A421945>two-line concept</>.

El sistema emite un mensaje de error y no le permitirá continuar con esta transacción hasta que se resuelva el error.

Respuesta del sistema

If these conditions are not fulfilled, the system cancels posting of the
IDoc or the SOA message.

¿Cómo arreglar este error?

Check the IDoc or SOA message. You may be able to edit the IDoc or SOA
message (for example, if the supplier transmitted the wrong order item
by mistake). Otherwise, you must inform the supplier and ask for the
invoice with the corrected data to be transmitted once again.
