testing Webservice in WS Navigator

Hi,

We are testing a webservice : Create Document (WSDL : http://<host Name>:<Port_name>/sap/bc/srt/xip/sap/ECC_DOCUMENTCRTRC?sap-client=100&wsdl=1.1) using Web service Navigator on CE 7.1 EHP1.

The error message we get in the result is "Exactly-once request cannot be locked: ED04E745F8164620BA21FD7F12F528E0 (error code: Could not find configuration entry for client 100)".

However the read document service is executing successfully.

Please help us in this.

Regards,

Sharath
