From My Trips - Create Expense Report service is opening in popup

Hello All,

We have activated business function HCM_ESS_WDA_1. After activating this function when I click on the "Create Expense Report" button from My Trips (POWL) service, it gets opened up in popup window.

Rather I want this to be opened up in the same window, like it used to in the past. Any throughts?

Thanks,

Bhushan
