How To Fix MD422 - &1 : &2 &3 (U4)

SAP Error Message - Details

• Message type: E = Error

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

• Message number: 422

• Message text: &1 : &2 &3 (U4)

Quelle est la cause de ce problème?

For one of the following reasons, the (non-fixed) order proposal could
not be planned on time:
On the basis of backward scheduling, the system calculated a start date
in the past. The system automatically switched to forward scheduling
and planned the order proposal in the future using the in-house
production time or the delivery time
On the basis of the planning time fence and a fixing type, the order
proposals are moved to the finish date of the planning time fence. With
this logic, order proposals must be correctly planned manually.
The date displayed is the date on which the receipt is to be available
for materials planning. This contains the goods receipt processing
time. If this is not equal to zero, the necessary goods receipt date is
also displayed for information purposes.

Réponse du système

The exception is displayed in the MRP list and the latest
stock/requirements list, along with the rescheduling date.
