• What is the cause and solution for SAP error message SMT080 - Parameter "e_ok" must be declared as an export parameter ?

  The SAP error message SMT080, which states "Parameter 'e_ok' must be declared as an export parameter," typically occurs in the context of SAP ABAP programming, particularly when working with function modules or methods in classes. This error indicates that the parameter e_ok is expected to be an export parameter but has not been declared as such in the function module or method signature.
  Cause:
  
  Incorrect Parameter Declaration: The parameter e_ok is likely defined in the function module or method but is not declared as an export parameter. In SAP, export parameters are used to return values from a function module or method to the calling program.
  Function Module Signature Mismatch: If the function module is being called from another program or function module, and the signature does not match the expected parameters, this error can occur.
  
  Solution:
  To resolve the error, you need to ensure that the parameter e_ok is correctly declared as an export parameter in the function module or method definition. Here are the steps to do this:
  
  
  Open the Function Module:
  
  Go to transaction SE37 (Function Module) or SE80 (Object Navigator).
  Enter the name of the function module that is causing the error.
  
  
  
  Edit the Function Module:
  
  Click on the "Change" button to edit the function module.
  
  
  
  Check Parameter Declaration:
  
  Navigate to the "Import/Export" tab.
  Ensure that e_ok is listed under the "Export Parameters" section. If it is not, you need to add it.
  
  
  
  Add the Parameter:
  
  If e_ok is missing, add it as an export parameter. Specify the data type and any other necessary attributes.
  
  
  
  Save and Activate:
  
  After making the changes, save and activate the function module.
  
  
  
  Test the Function Module:
  
  Test the function module to ensure that it works correctly and that the error no longer appears.
  
  
  
  Related Information:
  
  Export Parameters: In SAP ABAP, export parameters are used to return values from a function module to the calling program. They are defined in the function module's interface.
  Function Module Documentation: Always refer to the documentation of the function module to understand the expected parameters and their types.
  Debugging: If you continue to encounter issues, consider using the debugger to trace the execution and see how parameters are being passed.
  
  By following these steps, you should be able to resolve the SMT080 error and ensure that the parameter e_ok is correctly declared as an export parameter.
