try:

DATA: BEGIN OF TKOMP OCCURS 5,

HI,

instead of call function 'function_module'.

data:var(30) value 'function_module'.

and <b>call function var</b>.

this will be supported only when the importing,exporting,changing,tables parameters of the function modules match.other wise u should not use this type of calling.

rgds,

bharat.

Based on your different scenarios, store the name of function module in a variable.

Call function <var>

But here you must be sure about the interface of the function module and required to pass the mandatory fields while calling function module.

Sy-subrc check will let you know whether the function call is successful of not.
