ABAP Dump on Approving Travel Request

Question

Hello,
We are implementing MSS and when a manager is trying to open a Workitem to Approve a Travel request he gets the following ABAP Dump.
The following error text was processed in system R3Q : Value null of URL parameter SAP_FITV_PERSNO has the wrong type
The error occurred on application server <Hostname> and in work process 0 .
The termination type was: RABAX_STATE
The ABAP call hierarchy was:
Method: GET_REQUEST_INPLUG_PARAMETERS of program CL_WDR_CLIENT_APPLICATION=====CP
Method: INIT of program CL_WDR_CLIENT_APPLICATION=====CP
Method: IF_WDR_RUNTIME~CREATE of program CL_WDR_MAIN_TASK==============CP
Method: HANDLE_REQUEST of program CL_WDR_CLIENT_ABSTRACT_HTTP===CP
Method: IF_HTTP_EXTENSION~HANDLE_REQUEST of program CL_WDR_MAIN_TASK==============CP
Method: EXECUTE_REQUEST_FROM_MEMORY of program CL_HTTP_SERVER================CP
Function: HTTP_DISPATCH_REQUEST of program SAPLHTTP_RUNTIME
Module: %_HTTP_START of program SAPMHTTP
Don;t know what's causing it.
Any help would be highly appreciated.

Thanks for the reply.
According to the note : 1076144 I uploaded the valid XML Configuration file, still it gives the same error.
The Other Note : 1239932 is valid for ESS in MSS scenario , right?
Pls reply.
