Calling Web Dynpro ABAP popup from BADI

Hi all,

I am working on Appraisal Document application in HR. I want to call web dynpro popup and select more than 1 record from popup and comes back to the BADI where popup is called.

Is it possible or not ? if possible, how is it possible ?

a). I created one test web dynpro application and tried to use CALL_BROWSER function module but not working.

b). Created transaction code for WD application and used CALL Transaction statement but not working.

I got some CNTL_ERROR .

Regards

Venkat.
