SAP Error Message - Details

• Message type: E = Error

• Message class: MD - Material Requirements Planning (MRP)

• Message number: 404

• Message text: &1 : &2 (N2)

Quelle est la cause de ce problème?

In the MRP list, this exception message displays:
that the planned order was newly created in the last planning run
that the opening date of the planned order lies in the past

Comment corriger cette erreur?

The opening period is a time buffer that is planned to provide the
MRP controller with the time necessary for converting planned orders
or purchase requisition.
If the planned order can be converted (to a purchase requisition or
to a production order), it should be converted as quickly as possible.
