Hello S Kantheri,
In a SOAP scenario you have to send a request to the other server and then get a response (payload) back.
That means if you want to retrieve information from another server using SOAP you have to send a request to the server - therefore you need a SOAP receiver that sends the request and uses a certain SOAP action. Then the other server will respond to you request sending the payload you want.
I hope this helps. Please have a look at this for example:
Best regards,
Peter
