• What is the cause and solution for SAP error message EM078 - Describe the return field completely ?

  The SAP error message EM078, which states "Describe the return field completely," typically occurs in the context of SAP ABAP programming, particularly when dealing with function modules or BAPIs that return data. This error indicates that the return structure or field is not being populated or described correctly, which can lead to issues in processing the return values.
  Cause:
  
  Incomplete Return Structure: The return structure may not have all the required fields populated. This can happen if the function module or BAPI is not correctly implemented or if the calling program does not handle the return structure properly.
  Data Type Mismatch: There may be a mismatch in the expected data types between the calling program and the function module or BAPI.
  Missing Error Handling: If the return structure is not being checked for errors or messages, it may lead to incomplete information being passed back to the calling program.
  Incorrect Configuration: Sometimes, the configuration of the function module or BAPI may not be set up correctly, leading to incomplete return values.
  
  Solution:
  
  Check Return Structure: Ensure that the return structure is fully defined and that all necessary fields are being populated. This includes checking for fields like TYPE, ID, NUMBER, MESSAGE, and MESSAGE_V1 to ensure they are filled appropriately.
  Review Function Module/BAPI Implementation: If you have access to the implementation of the function module or BAPI, review the code to ensure that it correctly populates the return structure.
  Error Handling: Implement proper error handling in your calling program to check the return structure for any messages or errors. This can help identify issues early on.
  Data Type Verification: Verify that the data types in the calling program match those expected by the function module or BAPI.
  Testing: Test the function module or BAPI in isolation to ensure it returns the expected results. Use transaction codes like SE37 (for function modules) or SE80 (for BAPIs) to test and debug.
  Consult Documentation: Refer to the SAP documentation for the specific function module or BAPI to understand the expected return structure and any specific requirements.
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any known issues or patches related to the specific function module or BAPI you are using.
  Debugging: Use the ABAP debugger to step through the code and observe how the return structure is being populated.
  Community Forums: Engage with SAP community forums or support channels for additional insights or similar experiences from other users.
  
  By following these steps, you should be able to resolve the EM078 error and ensure that the return field is described and populated correctly.
