- 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:
- 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.
- 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.
- Version Mismatch: The version of the program in the database does not match the version in the ABAP runtime environment.
Solution:
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.
Check Transport Requests:
- Ensure that all necessary transport requests have been imported correctly. If there are missing objects, transport them again.
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.Check for Dependencies:
- Ensure that all dependent objects (like function modules, classes, or data elements) are also activated and in sync with the program.
System Restart:
- In some cases, a system restart may be necessary to clear any inconsistencies in the runtime environment.
Related Information:
