How to update Enterprise Portal's Expense Report

Hi all,

I've been trying to update the Expense Report in Enterprise Portal but I can't find where is that report located. I've modified TrvExpenseReport but that report is just linked to AX Client. 

This is part of the URL: /TrvExpenseReportsWorkerListPage.aspx?WMI=TrvExpenseReportsWorkerListPage&WCMP=uk01&WDPK=initial

And this is actually the URL of the report: /ManageExpenses/Enterprise%20Portal/TrvExpTablePrint.aspx?WP=isDlg%3d1&isDlg=1&WMI=TrvExpTablePrint&WTID=484&WKEY=%5b65534%3a5637146829%5d&WCMP=uk01&WDPK=initial&WHPV=5C92B9FE74CB052163C83C4AB45D722DE4B9CE93C0CBB5E25B3E95D4C86938ED&hideactionpane=1

Thanks in advance
