How To Fix MD128 - Starttermin gilt nicht für feste Zugänge

SAP Error Message - Details

• Message type: E = Error

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

• Message number: 128

• Message text: Starttermin gilt nicht für feste Zugänge

Was verursacht dieses Problem?

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

Systemantwort

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.

Wie behebe ich diesen Fehler?

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.
