How To Fix MD128 - La date de départ ne s'applique pas à des entrées fixes

SAP Error Message - Details

• Message type: E = Error

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

• Message number: 128

• Message text: La date de départ ne s'applique pas à des entrées fixes

Quelle est la cause de ce problème?

You want to take firmed receipts/issues into account and have scheduled
the start of the planning period.

Réponse du système

The start date of the planning period is valid for independent
requirements but not for firmed receipts/issue.
Otherwise, production orders, for example, could be included in the
planning run without considering the reservations earlier on the time
axis.

Comment corriger cette erreur?

It is less effective to set a start date in the future that takes
firmed receipts/issues into account.
It is more effective to schedule a start date in the past if the
independent requirements in the past (but after start date) are also to
be taken into account.
If a start date is not scheduled, independent requirements in the past
are not taken into account.
