  • What is the cause and solution for SAP error message PIC01120 - Material & has lock indicator in the MRP-set maintenance ?

This lock prevents any changes to the MRP settings for that material, which can be necessary for various reasons, such as ongoing planning processes or data integrity concerns.

    Cause:

    The lock indicator can be set for several reasons, including:

    Solution:

    To resolve the PIC01120 error, you can follow these steps:

    1. Check MRP Runs: Ensure that no MRP runs are currently active for the material. If an MRP run is in progress, you may need to wait until it completes.
