SOAP Error : Server was unable to process request. > Key cannot be null.#

[venkatesan_nagiah]

HI, When I process SOAP call from ABAP using class csoaptransporthttp->request_response, I am getting following error message:

"Server was unable to process request. > Key cannot be null.##Parameter name: key"

Is anybody as the clue to resolve this error ?

The error says that you miss the value for the key field. Can you use soap client tool (soapui or soapsonar) and test the same payload in it? See what result you get. We'll go further based on the output.
