  • What is the cause and solution for SAP error message SY091 - Load format of program & was changed ?

    The SAP error message SY091 indicates that the load format of a program has changed. This typically occurs when there have been modifications to the program or when the program has been recompiled. Here’s a breakdown of the cause, potential solutions, and related information:

    Cause:

    1. Program Changes: The program has been modified in a way that affects its load format. This can happen if the program is edited, or if there are changes in the underlying data structures or types.
    2. Transport Issues: If the program was transported from one system to another (e.g., from development to production), and the transport did not include all necessary objects or dependencies, it can lead to this error.
    3. Version Mismatch: The version of the program in the database does not match the version in the ABAP runtime environment.

    Solution:

    1. Recompile the Program:

      • Go to the ABAP Editor (transaction SE38 or SE80).
      • Enter the program name and choose to activate or recompile the program. This can help to synchronize the load format with the current code.
    2. Check Transport Requests:

      • Ensure that all necessary transport requests have been imported correctly. If there are missing objects, transport them again.
    3. Clear Buffer:

      • Sometimes, clearing the buffer can help. You can do this by using transaction code /n/SM12 to delete any locks or using /n/SM21 to check the system log for any related issues.
    4. Check for Dependencies:

      • Ensure that all dependent objects (like function modules, classes, or data elements) are also activated and in sync with the program.
    5. System Restart:

      • In some cases, a system restart may be necessary to clear any inconsistencies in the runtime environment.

    Related Information:

    • Transaction Codes:
      • SE38: ABAP Editor
      • SE80: Object Navigator
      • SE11: Data Dictionary
      • SE37: Function Module
    • SAP Notes: Check SAP Notes for any known issues related to this error message. You can search for SY091 in the SAP Support Portal.
    • Debugging: If the issue persists, consider debugging the program to identify where the load format mismatch is occurring.

    Conclusion:

    The SY091 error is typically related to changes in the program's load format due to modifications or transport issues. By recompiling the program, checking transport requests, and ensuring all dependencies are activated, you can usually resolve the issue. If problems persist, further investigation into system logs and debugging may be necessary.
