  Check Data Length: Review the data being sent to ensure that the parameter in question has the correct length as specified in the error message. Adjust the data accordingly.
  
  
  Review Mapping/Transformation Logic: If you are using a mapping tool (like SAP PI/PO), check the mapping logic to ensure that it correctly transforms the data to meet the expected lengths.
  
  
  Configuration Review: Verify the configuration settings in the EDI or IDoc setup to ensure that they align with the expected data structure. This includes checking the relevant segments and fields.
  
  
  Testing: After making adjustments, conduct tests to ensure that the data is processed correctly without triggering the error.
