    Error Message

    W_CB399: Material Group 2 &1 does not exist

    • &1 is a placeholder for the actual material group value that the system could not find.

    Cause

    This warning message occurs when you try to create or process a material master record or related transaction, and the system cannot find the specified Material Group 2 in the customizing tables.

    • Material Group 2 is a classification field used in some SAP modules (e.g., Logistics, Material Management) to further categorize materials.
    • The system expects the material group to be predefined in the customizing table but it is missing.
    • This can happen if:
      • The material group was not maintained in the system.
      • There is a typo or incorrect material group code entered.
      • The material group is referenced in a transaction but not yet created in the system.

    Where is Material Group 2 maintained?

    Material Group 2 is usually maintained in the Customizing under:

    • SPRO ? Logistics - General ? Material Master ? Basic Settings ? Material Groups ? Define Material Groups

    Or in some systems, it might be under:

    • SPRO ? Logistics - General ? Material Master ? Classification ? Define Material Groups

    The exact path can vary depending on the SAP version and module.


    Solution

    1. Check the Material Group 2 value:

      • Verify the material group code you are trying to use.
      • Make sure it is correct and matches the expected format.
    2. Maintain the missing Material Group 2:

      • Go to the customizing transaction (usually SPRO).
      • Navigate to the path for defining material groups.
      • Create or maintain the missing material group code.
      • Save and transport the changes if necessary.
    3. Check master data and transaction input:

      • Ensure that the material master or transaction data references a valid material group.
      • Correct any typos or incorrect entries.
    4. If the material group is optional:

      • Sometimes this message is a warning (W_ prefix) and not an error.
      • You can proceed but it is recommended to maintain the material group for consistency.

      • MM01/MM02 - Create/Change Material Master
      • SPRO - Customizing Implementation Guide

      • T023 - Material Groups (Material Group 1)
      • T023T - Material Group Texts
      • For Material Group 2, there might be a custom or additional table depending on configuration.
    • Note: Material Group 2 is not standard in all SAP systems; it might be a custom field or part of a specific industry solution or enhancement.


    Summary

    Aspect Description
