    The SAP error message CM_MRP_BUFFER006 indicates that there are no materials defined for cache calculation in the context of Material Requirements Planning (MRP). This error typically arises when the system attempts to perform a cache calculation for MRP but cannot find any materials that meet the criteria for the calculation.

    Cause:

    1. No Materials Defined: The most common cause is that there are no materials assigned to the MRP area or the specific planning run you are trying to execute.
    2. Incorrect MRP Area Configuration: The MRP area may not be properly configured, or the materials may not be assigned to the correct MRP area.
    3. Selection Criteria: The selection criteria used for the MRP run may not include any materials, either due to filters or incorrect parameters.
    4. Inactive Materials: The materials may be inactive or not relevant for the MRP run.

    Solution:

    1. Check Material Master Data: Ensure that the materials you expect to be included in the MRP run are correctly defined in the material master. Check the MRP views to confirm that they are set up properly.
