  • What is the cause and solution for SAP error message WB2B2112 - Assignment UoM &1 difers from the base UoM &2. ?

    The SAP error message WB2B2112 indicates that there is a discrepancy between the unit of measure (UoM) assigned to a particular item and its base unit of measure. This error typically arises in scenarios involving inventory management, sales orders, or purchasing where the system expects a consistent unit of measure.

    Cause:

    1. Unit of Measure Mismatch: The item is being processed with a unit of measure that does not match the base unit of measure defined in the material master.
    2. Configuration Issues: There may be incorrect settings in the material master data or in the configuration of the UoM in the system.
    3. Data Entry Errors: Manual entry of UoM in transactions may lead to inconsistencies if the user selects a UoM that is not compatible with the base UoM.

    Solution:

    1. Check Material Master Data:

      • Go to the material master record (transaction code MM03) and verify the base unit of measure and the alternative units of measure.
      • Ensure that the UoM being used in the transaction is defined as an alternative unit of measure for the material.
    2. Review Transaction Data:

      • Check the transaction where the error occurred (e.g., sales order, purchase order) and ensure that the UoM used matches the allowed UoMs for that material.
    3. Adjust UoM in Transaction:

      • If the UoM used in the transaction is incorrect, change it to match the base UoM or one of the alternative UoMs defined in the material master.
    4. Configuration Settings:

      • If necessary, review the configuration settings for UoM in the SAP system (transaction code SPRO) to ensure that they are set up correctly.
    5. Consult Documentation:

      • Refer to SAP documentation or help resources for further guidance on UoM settings and configurations.

    Related Information:

    • Unit of Measure Types: Understand the different types of UoMs (base UoM, alternative UoM, sales UoM, etc.) and how they interact in SAP.
    • Material Master Views: Familiarize yourself with the different views in the material master that affect UoM settings, such as Basic Data, Sales, and Purchasing views.
    • SAP Notes: Check for any relevant SAP Notes that may address specific issues or bugs related to UoM handling in your version of SAP.

    By following these steps, you should be able to resolve the WB2B2112 error and ensure that the UoM used in your transactions aligns with the base UoM defined in the material master.
