It is all yes all explained in there on how to call a function module either with literal 'bladibla' or through a variable.

Kind regards, Rob Dielemans

Pass a variable as func name and this can be fileld from your custom table.

data: ld_funcname TYPE string.

call fundtion 'func_name'.

Hello guys,

I also thought this question credited a STFW

But a slight thought & i changed my mind. If the interface params for all the FMs in the custom table are same, then the question merits an STFW.

But what if the interface params are diff ? How do we handle this situation ?

Hi Suhas,

what about declaring the signatures as reference types ?

Hi Keshav,

Which means at the end of the day all the FMs need to have the same interface if i am not mistaken. Please correct me if i am wrong.

How the OP handles this depends on this business requirements.

Hello Keshav,

But from which table you get the FM parameters. TFDIR does not help.

PS: I may sound dumb, but i did not google / search in SDN. So please bear with my ignorance

Hi Suhas,

The reference types will not be applicable as you said,

what i think is the abap_func_parmbind in type pool abap is use.

just by appending all the signatures into it

and the passing it to a fm created.

check the standard include LV69AF21, how the fm's PRICING_SUBSCREEN_PBO and PRICING_SUBSCREEN_PAI gets called.

The signatures in each fm are different.
