  Cause:

  Data Validation: Before processing the data, implement checks to ensure that the field is null when required. This can help prevent the error from occurring.
  
  
  Debugging: Use the SAP debugger to trace the execution flow and identify where the field is being set. This can help pinpoint the exact location in the code or process where the issue arises.
