I have a question on smartforms, I managed to create one and generated the function module but now when I call the function module of the form in my report I get an error. Please advise on what to do.
The code below that I am using.

Try to avoid hard coding the function module (SSF_FUNCTION_MODULE_NAME)  - importing parameter,
instead declare a variable and then pass that value to that next calling function module .
Take a look at the code...below
