@Sandhya_Gajare & @muhamed_fasil: Hey both, just a short addition from my side. From expierience it can be dangerous to use activities that can fail in the state transition, as they are not covered by the frameworks exception handling. Therefore, I would suggest a try catch around the send activity. Better would be to handle this in the end state, as it is covered with try catch again. Otherwise the chance of an undocumented / unhandled process end my be possible. Maybe I am seeing this wrong, so feel free to test for your self.
