Basic information about <DS:DE.CATEXCMD>External variants</>

System Response

if parameter default values are to be saved in an external file, it
must first be defined in the test procedure.

• What is the cause and solution for SAP error message TT186 - No exportable parameters with default values exist ?

  The SAP error message TT186: No exportable parameters with default values exist typically occurs in the context of function modules or methods in ABAP when you are trying to call a function or method that does not have any parameters that can be exported with default values. This can happen for a variety of reasons, and understanding the cause and finding a solution requires a bit of investigation.
  Cause
  
  
  Function Module/Method Definition: The function module or method you are trying to call may not have any parameters defined as export parameters with default values. Export parameters are those that are intended to return values to the calling program.
  
  
  Incorrect Call: You might be calling the function or method incorrectly, or you might be expecting it to return values when it is not designed to do so.
  
  
  Parameter Types: The parameters defined in the function module or method may not be marked as export parameters, or they may be input parameters only.
  
  
  Solution
  
  
  Check Function Module/Method Definition:
  
  Go to the function module or method definition in the ABAP Workbench (transaction SE37 for function modules or SE80 for classes/methods).
  Verify the parameters defined. Ensure that there are export parameters with default values.
  
  
  
  Modify the Call:
  
  If the function or method does not have export parameters, you may need to adjust your call. If you are expecting a return value, check if there are any other parameters (like changing parameters or returning parameters) that you should be using instead.
  
  
  
  Use Correct Parameters:
  
  If the function/module is designed to work with input parameters only, ensure you are passing the correct input values and handling the output as needed.
  
  
  
  Consult Documentation:
  
  Check the documentation for the function module or method to understand its intended use and the parameters it supports.
  
  
  
  Debugging:
  
  If you are still unsure, you can use the debugger to step through the code and see what parameters are being passed and how the function/module is being executed.
  
  
  
  Related Information
  
  Export Parameters: These are parameters that allow data to be passed back to the calling program. They are defined in the function module or method signature.
  Input Parameters: These are parameters that are used to pass data into the function/module but do not return any data.
  Changing Parameters: These parameters can be used to pass data into the function/module and can also be modified by the function/module to return data back to the caller.
  
  Example
  If you have a function module Z_MY_FUNCTION defined as follows:
  
  Import Parameters: IV_PARAM1
  Export Parameters: None
  
  And you try to call it like this:
  DATA: lv_result TYPE string.
  CALL FUNCTION 'Z_MY_FUNCTION'
    EXPORTING
      IV_PARAM1 = 'Some Value'
    IMPORTING
      EV_RESULT = lv_result.  " This will cause TT186
  You will receive the TT186 error because there are no export parameters defined in the function module.
  In summary, to resolve the TT186 error, you need to ensure that you are calling the function or method correctly and that it has the appropriate parameters defined for your use case.
