Custom Role - To show "Create Expense Report" Iview

Hi,

I'm creating end user roles in the portal side and in that, i want to add in the "Create Expense Report" Iview or Page, which exists in Portal Content -> Travel & Expenses.

But after adding the Iview or Page, i could not able to see the iview or page in the menu.

But if i add the whole "Travel & Expenses" page, can able to see all "My Trips & Expenses", "Create Expense Report" etc.

What could be the problem?

Thanks.
