hi Ulrich
we are already calling the same way
but my requirement is that the ECC program shud get 'completed'
the background job in sm37 should be completed, finished.
the program in SRM should have got started. and when it will get finished, then the results shud be sent back to ECC.
Starting new task is asynchronous in way of connection but as a functionality, the calling program is not finished while the RFC is running.
thanks
bhakti
