Hi Rashmi
this is very weird that you have a communication arrangement, you ping from there and get 405 error, which is fine, but then you create a message and get nothing created. I haven't seen that before. I'm afraid you need to create a ticket - you can send it to SAP and put the number that starts with a '3' back in this conversation. I think we need to watch you send a message -it's like the action you are taking is not the same as what is in the communication arrangement. When you create the ticket could you include screenshots of:
* communication arrangement with ping message
* account you are creating in C4C
* refresh of the web service monitor with no messages
