Hi VeeraBrahmam,
I don't think it is possible without changing the driver-program itself.
Of course, a solution would be to set the get_otf = abap_true and afterwards send the email by your own, that means develop a additional part using cl_bcs.
That is the only solution I got now in my mind. Now you have to decide, if it is worse to develop this. This will take some hours for sure
