  • What is the cause and solution for SAP error message GB304 - Only make one entry in this line (either constant or exit) ?

    The SAP error message GB304 ("Only make one entry in this line (either constant or exit)") typically occurs in the context of defining a condition in a pricing procedure or when working with condition records in SAP. This error indicates that there is a conflict in the entries made in a specific line of the condition table, where both a constant and an exit have been defined simultaneously, which is not allowed.

    Cause:

    1. Conflicting Entries: The error arises when both a constant value and an exit (a custom function or routine) are defined for the same condition line. SAP expects either a constant or an exit, but not both.
    2. Configuration Issues: This can happen during the configuration of pricing procedures or condition types where the settings are not aligned correctly.

    Solution:

    1. Review Condition Configuration:

      • Go to the relevant pricing procedure or condition type configuration in the SAP system.
      • Check the specific condition line that is causing the error.
      • Ensure that you have either a constant value or an exit defined, but not both.
    2. Modify the Entries:

      • If you find both a constant and an exit defined, decide which one is necessary for your business logic.
      • Remove the unnecessary entry (either the constant or the exit) to resolve the conflict.
    3. Testing:

      • After making the changes, test the pricing procedure or condition record to ensure that the error is resolved and that the desired functionality is achieved.

    Related Information:

    • Transaction Codes: You may need to use transaction codes like V/08 (for condition types) or V/06 (for pricing procedures) to access and modify the relevant settings.
    • Documentation: Refer to SAP documentation or help files for detailed information on configuring pricing procedures and condition types.
    • SAP Notes: Check for any relevant SAP Notes that might provide additional insights or solutions related to this error message.

    If the issue persists after following these steps, it may be beneficial to consult with an SAP functional consultant or support team for further assistance.
