  • What is the cause and solution for SAP error message WZRE_PRX504 - Invoice request &1 has been changed ?

    Certainly! Here's detailed information about the SAP error message:


    SAP Error Message:

    WZRE_PRX504 Invoice request &1 has been changed


    Cause:

    This error message typically occurs when an invoice request (or invoice document) that you are trying to process or reference has been modified or updated by another user or process after you initially accessed it. The system detects that the data has changed since you last read it, which can lead to inconsistencies or conflicts if you proceed without refreshing the data.

    In other words, the invoice request number &1 (where &1 is replaced by the actual invoice request number) has been changed in the database, and your current session or transaction is working with outdated data.


    When does it occur?

    • When you try to post, change, or reference an invoice request that has been updated by another user or process.
    • When there is a concurrency conflict due to simultaneous access or update.
    • When the system uses optimistic locking and detects that the data has changed since it was last read.

    Solution:

    1. Refresh the Data:

      • Exit the current transaction or screen.
      • Re-enter the invoice request or reload the data to get the latest version.
      • This ensures you are working with the most current data.
    2. Check for Concurrent Changes:

      • Verify if another user or process has updated the invoice request.
      • Coordinate with other users if necessary to avoid simultaneous changes.
    3. Reprocess the Invoice Request:

      • After refreshing, try to perform the intended action again (e.g., posting, changing).
    4. Check for Custom Enhancements or User Exits:

      • If this error occurs frequently or unexpectedly, check if there are any custom developments or user exits that might be causing premature updates or locks on the invoice request.
    5. System Notes and OSS Messages:

      • Check SAP Notes or OSS messages for any known bugs or patches related to this message.

    Related Information:

    • This message is related to data consistency and concurrency control in SAP.
    • It is often seen in modules dealing with invoicing, billing, or financial document processing.
    • The message class WZRE_PRX suggests it is related to invoice processing or a specific add-on or industry solution (e.g., SAP IS-U for utilities).
    • If you are working in a specific industry solution (like IS-U), check the relevant documentation or SAP Notes for that module.

    Summary:

    Aspect Details
    Message WZRE_PRX504 Invoice request &1 has been changed
    Cause Invoice request was changed by another user/process after you accessed it
    Effect Data inconsistency or concurrency conflict
