MSS Travel Expenses Approvals

Hi,

While processing the UWL ESS/MSS for Travel Expenses, when we select a trip and press the view trip receipts button we get a dump message in the new window saying that 'Value null of URL parameter WI_ID has the wrong type ' .

The following error text was processed in the system DU1 : Value null of URL parameter WI_ID has the wrong type.

The error occurred on the application server XXXXXX and in the work process 0 .

The termination type was: RABAX_STATE

The ABAP call stack 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 of program CL_HTTP_SERVER================CP

Function: HTTP_DISPATCH_REQUEST of program SAPLHTTP_RUNTIME

Module: %_HTTP_START of program SAPMHTTP

I debug the class method : cl_wdr_client_application-> GET_REQUEST_INPLUG_PARAMETERS

There seems to be two duplicate paramters id WI_ID with one filled value and other with null and its seems that the null value is been passed to the custom webdynpro Window view import parameters.

Any ideas what might be causing this problem?

Thanks,

Kumar

    as you already found out that the problem is the second duplicate parameter with initial value. I would try to find out why that second parameter is coming and from where it is added second time.

    You can also change the WDA inbound plug to read the URL parameter "All parameters" and not only the WI_ID. Then you can loop through the parameters and fetch the correct WI_ID.
