Netwaever portal 7.3 travel request forms(PDF) inUWL

Hi Experts,

We are implementing Travel module. We have registered the standard task TS20000118. When approver tries to see the travel request form in portal uwl
it displays travel request details in SAP GUI screen instead of PDF.

When we open the task TS20000118 in UWL from task item its shows the screen as per attcahed here.

After clicking on the link "EmployeeTrip:Trip No SAP R3 GUI screen opens, instead of that we want PDF form.

Please let me know is there any configuration missing.

Regards,

Rashmi V.
