MF326 - Overview

• Message type: E = Error

• Message class: MF - MPS planning and evaluation

• Message number: 326

• Message text: For sales order & &, no requirements exist in the master plan

What causes this issue?

When no MRP relevant requirement exists, an order report cannot be
generated.
The following causes are possible:
1. For the "make-to-stock production" planning strategy, sales orders
are only displayed as information. Customer requirements are not taken
into consideration in MRP with this planning strategy, therefore no
replenishment elements can be determined in the order report for sales
orders.
2. The sales order item was rejected.
3. A delivery exists that covers the complete sales order item.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
