Calling Function module parameters Dynamically

Former Member — Fri, 11 Jan 2019 10:12:05 GMT

Hi Folks,

I am having a requirement where in user enters the Function module name in Selection screen and based on the FM name i need to generate its Importing,Exporting and TABLES parameters dynamically.

Once i get these parameters i need to call that FM with the above parameters and fetch the Data returned from that FM.

Let me know your views on how to achieve this.

Thanks,

Hi Prashant,

The issue is we don't know which function module will be called at runtime. Based on user entry we need to get FM parameters.

Regards,

You can get the function module template using a function call. I have used that quite successfully in previous projects called 'FUNCTION_STUB_GENERATE'. That gives you the parameter lists etc. You then use the function module parameter table (not table parameters...) to build your parameters. It's actually quite easy.

Bindu all you asking for is SE37 functionality where you enter FM name press F8 and then add your testing parameters and test. Why dont you reuse that?
