Hi Sanjeev,
If I understand your question properly, then do the BDC recording for all the above fields...but
before passing data to BSEG-WRBTR and BSEG-DMBTR just check if BKPF-WAERS NE 'INR' then only pass the required fields BSEG-WRBTR and BSEG-DMBTR to screen/BDC session.
Hope this helps.
Regards
Sri
