Dynamic parameters in function module

Former Member — Fri, 09 Mar 2012 11:12:50 GMT

Hi. I need to write a program that can call various different function modules based on what the user inputs.

For example, if the user chooses "BAPI_USER_GET_DETAIL" I need to then call that function module. There is a list of about 30 functions they can choose from.

I can read in the function interface using FUNCTION_IMPORT_INTERFACE and have got the import, changing and tables parameters being entered in an editable ALV.

Now I just need to work out how to call the function module.

I could spend ages hard coding all the various combinations, but what I would like to do is call the function totally dynamically.

I know this wouldn't work, but this sort of thing:

CALL FUNCTION p_funct

EXPORTING

<imp_1> = <val_1>

<imp_2> = <val_2>.

Has anyone got any ideas?

Thanks a lot,

Dave.

What release are you working with? I think from 6.10 the options PARAMETER-TABLE and EXCEPTION-TABLE were added to the CALL FUNCTION statement for such purposes.

As always, ABAP F1 help has the details.

Hi. I think you've solved it, thanks a lot.

Just checking it all now, will be back shortly.

Can't believe it was that simple, spent ages looking through SDN and google. I was searching for dynamic function, not bapi, so I missed that posting too.

Regards,

Dave.
