- Loop contains an illegal element. Operation not performed ?The SAP error message "37135 Loop contains an illegal element. Operation not performed" typically occurs in the context of SAP workflows or when dealing with certain data structures in ABAP programming. This error indicates that there is an issue with the structure of a loop in your code or workflow definition, where an illegal or unexpected element has been encountered.
Cause:
- Invalid Loop Structure: The loop may be trying to iterate over a data structure that contains elements that are not valid for the operation being performed.
- Data Integrity Issues: The data being processed may have inconsistencies or invalid entries that lead to the loop encountering unexpected elements.
- Workflow Configuration: If this error occurs in a workflow, it may be due to incorrect configuration or an invalid path in the workflow definition.
- Programming Errors: In ABAP code, it could be due to incorrect handling of internal tables or data structures.
Solution:
- Check Loop Logic: Review the loop structure in your code or workflow. Ensure that the loop is correctly defined and that it only processes valid elements.
- Validate Data: Before entering the loop, validate the data being processed to ensure that it does not contain any illegal or unexpected elements.
- Debugging: Use debugging tools to step through the code and identify where the illegal element is being introduced. This can help pinpoint the exact cause of the error.
- Review Workflow Configuration: If the error is related to a workflow, check the workflow configuration for any incorrect paths or elements that may not be valid.
- Error Handling: Implement error handling to gracefully manage situations where illegal elements are encountered, allowing the program to either skip them or log them for further investigation.
