• What is the cause and solution for SAP error message CL_SADL_GW_MDE_MSG002 - Line is too long ?

  The SAP error message CL_SADL_GW_MDE_MSG002 with the description "Line is too long" typically occurs in the context of SAP Gateway and the SAP ABAP programming environment. This error indicates that the data being processed exceeds the maximum length allowed for a line in the context of the operation being performed, such as when handling data in a table or during serialization/deserialization processes.
  Causes:
  
  Data Length Exceeding Limits: The most common cause is that the data being sent or received exceeds the maximum length defined for a field or structure in the ABAP Dictionary.
  Incorrect Data Mapping: If there is a mismatch between the data structure in the backend and the expected structure in the frontend (e.g., OData service), it can lead to this error.
  Large Text Fields: If you are trying to send large text fields (like long descriptions or notes) that exceed the defined limits, this error can occur.
  Configuration Issues: Misconfiguration in the OData service or the way the data is being serialized can also lead to this error.
  
  Solutions:
  
  Check Data Length: Review the data being processed to ensure that it does not exceed the maximum length defined in the ABAP Dictionary. You may need to truncate or split the data if it is too long.
  Adjust Data Structures: If you control the backend service, consider adjusting the data structure to accommodate larger data sizes. This may involve changing the data type of fields in the ABAP Dictionary.
  Modify OData Service: If you are using an OData service, ensure that the service is correctly configured to handle the expected data sizes. You may need to regenerate the service or adjust the metadata.
  Error Handling: Implement error handling in your application to catch this error and provide meaningful feedback to the user or log it for further analysis.
  Testing: Test with smaller data sets to confirm that the issue is related to data length. Gradually increase the size to identify the threshold that triggers the error.
