Hi,

Create a structure S_STRUC in the top include of the function group..Which should be of the same structure of the IMPORTING structure.

MOVE the value from the IMPORTING structure to the top include structure S_STRUC.

S_STRUC = IM_STRUC.

Then you can use the structure S_STRUC any where in your screen..

Thanks,

Hi,

The best way would be to EXPORT the parameters from one part of your program and then IMPORT them back when needed.

Please click the link below to know about IMPORT/EXPORT commands in SAP.

This should solve your problem.

Hi,

I don't understand your question..

If you are calling the FM in a user exit...The value will be passed in the exporting parameter right..Which means in the calling place..You will have that data..

Example.

USEREXIT code..

***In the user exit the value is available in the WA_STRUC

CALL FUNCTION 'ZZZZ'

EXPORTING EX_STRUC = WA_STRUC.

FUNCTION ZZZZ.

***IMPORTING EX_STRUC

**Now you have the value in the work area EX_STRUC.

ENDFUNCTION.

Thanks

You have to declare the structure S_STRUC in the top include of your function group.

IM_STRUC will be your importing parameter..

IN the function module you should give

S_STRUC = IM_STRUC.

Hi,

Ok..Let me explain clearly..

Assuming this is your Z Function module code..

FUNCTION z_call_screen.

*"----

""Local interface:

*" IMPORTING

*" IM_STRUC TYPE MARA

*"----

Move the value IM_STRUC to the top include structure..
The structure S_STRUC should be declared in the top include of the FM.
In the menu..GOTO -> GLOBAL DATA..
declare the structure S_STRUC which should of type MARA.

S_STRUC = IM_STRUC.

CALL the screen.

CALL SCREEN '0100'.

ENDFUNCTION.
