go thru the code below

* calling the BAPI to update the Asset Master AS02
  loop at it_final into is_final.

Hi Suraj,

BAPI's are generally RFC (Remote Function Calls) enabled function modules. In this type of FM's, we can not pass a parameter by reference. So, U see only Pass by Value option selected in both import and export parameters.

Actual parameters: Lets suppose that u r calling a subroutine where u have different kind of parameters like TABLES, USING and CHANGING... these parameters are called as Actual Parameters...

For Example: PERFORM F_GET_DATA TABLES G_ITAB

USING LV_VAR1

CHANGING LV_VAR2.

Here G_ITAB, LV_VAR1 and LV_VAR2 are actual parameters...

Formal Parameters: Names given to the actual parameters in subroutine definition are called as formal paramaters or formal names given to actual parameters...

For Example: FORM F_GET_DATA TABLES P_G_ITAB

USING P_LV_VAR1

CHANGING P_LV_VAR2.

ENDFORM.

Here P_G_ITAB, P_LV_VAR1 and P_LV_VAR2 are formal parameters...

Hope it clears your doubt...

Regards,

Phani.
