Data Entry widget - unable to map import parameters of BAPI Wrapper

Hi,

I am trying to create a widget for data entry (something like Opportunity Create). I plan to use existing BAPI wrappers for this, and need to map some import parameters to my widget fields.

Any idea regarding ways to do this? Presently, the drag-and-drop approach of mapping parameters doesn't seem to be working.

Thanks in advance,

Sandeep.
