3423157 - Cannot assign a custom MRP controller to a material in the master data

Symptom

You have maintained your own MRP controller in SSCUI 101114 - Define MRP Controllers in your Productive system. However, when you try to assign it to a material's master data via Change Material app, you get the error message "The MRP controller *** for plant **** cannot be used, because it is locked". (Message no. WRF_MATERIAL109)

Environment

SAP S/4HANA Public Cloud

Cause

The MRP controller is locked by the ongoing change project in the Quality system which contains the MRP controller related configurations.
Although this SSCUI is "Redo in P" which means you can make the configurations directly in the P system. However, the unfinished change request in Q system will still affect the use of the MRP in the P system.

Resolution

Please finish the corresponding change project in the Q system first. Then you can use the MRP controller in the P system.
