Hi, Sreenivasan
Ping Web Service can be done by the following 5 steps.
lo_http_client TYPE REF TO if_http_client,
1) cl_http_client=>create_by_url (get lo_http_client object)
2) lo_http_client->send
3) lo_http_client->receive
4) lo_http_client->response->get_status
5) lo_http_client->close
Best regards,
Daniel
