  Modify Data Types: If you find that the data type is not supported, consider changing it to a supported type. For example, if you are using a complex structure, try to break it down into simpler types or use a different representation.

  Test with Different Data: Sometimes, the issue may arise from specific data being passed. Test the web service with different input data to see if the error persists.
  Check for Updates: Ensure that your SAP system is up to date with the latest support packages and notes, as there may be fixes or enhancements related to web service handling.
