  Modify the Report or BAdI: If you are working with a custom report or BAdI, you may need to modify the logic to ensure that it adheres to the supported data structures. This may involve changing how data is grouped or displayed.
  Consult Documentation: Refer to SAP documentation or help resources related to the specific module or tool you are using. There may be guidelines on how to structure data correctly.
  Testing: After making changes, thoroughly test the report or BAdI to ensure that the error does not occur again and that the output is as expected.
