Hi Kranthi,
Well, no - come on. You are surely experienced enough yourself now to do some of that trouble-shooting? First check the GTS logs, and then the SM58 failure list if no logs exist. If nothing there, then set a break-point in Function Module /SAPSLL/CD_SD0C_R3 and see where you get to.
Let us know if you get stuck on some detail.
Regards,
Dave
