• What is the cause and solution for SAP error message SMT098 - Method &1:Transformation methods may not contain parameter E_OK ?

  The SAP error message SMT098, which states "Method &1: Transformation methods may not contain parameter E_OK," typically occurs in the context of ABAP programming, particularly when dealing with transformation methods in the SAP system.
  Cause:
  The error arises when a transformation method is defined with an output parameter named E_OK. In SAP, transformation methods are used to convert data from one format to another, and they are expected to follow specific conventions. The parameter E_OK is reserved for certain standard uses, and including it in your transformation method definition violates these conventions.
  Solution:
  To resolve this error, you should:
  
  
  Check the Method Definition: Review the definition of the transformation method that is causing the error. Look for any parameters named E_OK.
  
  
  Rename the Parameter: If you find that E_OK is being used as a parameter in your transformation method, rename it to something else that does not conflict with SAP's reserved naming conventions. For example, you could use E_SUCCESS or E_RESULT.
  
  
  Adjust the Method Logic: After renaming the parameter, ensure that any logic that references E_OK is updated to use the new parameter name.
  
  
  Test the Transformation: After making the changes, test the transformation method to ensure that it works as expected and that the error no longer occurs.
  
  
  Related Information:
  
  
  Transformation Methods: In SAP, transformation methods are often used in the context of data migration, data conversion, or data mapping scenarios. They are defined in ABAP classes and are part of the data processing logic.
  
  
  ABAP Naming Conventions: Familiarize yourself with ABAP naming conventions and reserved keywords to avoid similar issues in the future. SAP has specific guidelines for naming parameters, methods, and classes.
  
  
  SAP Documentation: Refer to the official SAP documentation for more details on transformation methods and best practices in ABAP programming.
  
  
  By following these steps, you should be able to resolve the SMT098 error and ensure that your transformation methods are correctly defined.
