• Message number: 327

• Message text: La asignación ya no se puede modificar porque ya existe ME

¿Qué causa este problema?

You have attempted to revoke the assignment of a WIP batch to an order
item. This is not possible because a goods receipt has already been
posted against this order item.

Respuesta del sistema

The system terminates the function.

¿Cómo arreglar este error?

If you have to revoke the assignment, you must first reverse the goods
receipt. You can then revoke the assignment of the WIP batch to the
order item.
If you are entering goods receipts for the order via the confirmation
CO11N or COR6N), you must cancel the confirmation in which you posted
the goods receipt and all subsequent confirmations using the function
<ZK>Cancel Confirmation for Production Order</> (CO13) or <ZK>Cancel
Confirmation for Process Order</> (CORS).
If you are entering goods receipts for the order using the goods
movement transactions of Inventory Management (e.g. transaction MIGO),
you must cancel the corresponding material document.
