Hello Naveen,
If the connection is available (test with SM59 + Connection identifier),
after choosing your Connection you can test the connection:
you might find the idocs with the daate when they where sent in SM58:
The message says in this case there was no service, there might also be other errors like "wrong password" and so on.
After solving the error, you can restart sending the idoc from this screen.
Hope this helps .
Regards,
Gerlinde
