SAP Error Message - Details

• Message type: E = Error

• Message number: 426

• Message text: &1: &2 (P3)

Was verursacht dieses Problem?

In Customizing, no specification has been made to allow the adjustment
of the order start date to the production start date.
However, the production start date calculated using the routing lies
before the order start date calculated using the in-house processing
time in the material master record.
This could mean that the times in the material master record or in the
routing are incorrect. If the in-house processing time in the material
master record is too small, this may lead to material shortages.

Systemantwort

This exception is displayed in the MRP list and in the current
stock/requirements list.

Wie behebe ich diesen Fehler?

Check the times in the material master record and in the routing.
