Using Process Automation to export Crystal Report to a historical instance

We have a custom job that we run on a regular basis and I have build a Crystal Report off of the data that this report creates.  I am looking for a way to have IPA kick off the URL to create a historical instance of the report in Reporting Services.  I know what the URL is and have tested entering it in the browser and verified that the syntax is correct.

We have create a WebRun node in a process, but we cannot get it to work.  Has anybody done this before and do you know what our values would be in the node?

I have the Connection information - Override connection selected and then entered our URL for Reporting Services in the Web root and the lawson user and password.
The Call type is Lawson HTTP Call
The Call information has the following in Web program  ers/ersRequestHandler.jsp?DisplayReport=true&SUBCMD=EXPORT_REPORT&REPORTID=79&InstanceId=0&OUTPUTTYPE=&Refresh=true&Destination=Disk&OuterWrapper=true&NEWREPORT=true&EFSSESSIONKEY=TrVMSCJGr6Gw0Eam76zxEEg&INSTANCENAME=20140908&NEWREPORT=true
I do not have anything else in the Succes string, Post string or Content Type

Any pointers would be appreciated.

thank you

Jon
