Function module Dynamic call

former_member156446 — Mon, 13 Jul 2015 16:05:43 GMT

I am trying to make a dynamic call of function, I am fetching data from fupararef table and making dynamic calls to functions using the below code


*-- Main call
     CALL FUNCTION function
       PARAMETER-TABLE ptab
       EXCEPTION-TABLE etab.

In debug, when I hog into the function the import parameters are blank even though ptab table is filled correct.

The value is being passed as a ref to data. Not sure why the import parameters A and B are blank in the function( its a simple function to add a + b = c.

Parameter A and B should be passed as EXPORTING (ABAP_FUNC_EXPORTING = 10) in field KIND. I think you are passing that as IMPORTING (ABAP_FUNC_IMPORTING = 20). Parameter C should be IMPORTING (20).

Now, you may ask why it didn't raise an error as those parameter A and B are not defined as EXPORTING in the FM. The reason is - Dynamic FM call ignores all the parameters which don't exist. Read more at - ABAP Call FM Dynamically with Mystery Parameters! | ABAP Help Blog
