Not able to Drilldown to Source document from Payment Process Request->Selected Payments

Currently we are processing payment in PPR(Batch Payment). Once Payment is routed for approval of manager, he opens Payment batch and he can see details of Documents Payable(Invoice/Payment Request) such as Reference Number, Document Date, Amount to be paid, etc. Manager wants to have a drill down Enabled so that he can click on Document Reference number and verify source document(Invoice/Expense Report).

Currently he has to copy document number from PPR and then search individual document in Manage Invoices/Manage Expense Reports page using new tab, which is time consuming activity.

PPR Status - Payments approval initiated
