PeopleSoft 9.2 Expense - Receipt Management

Hi,

We are in the process of implementing PeopleSoft 9.2 Expense - Receipt management functionality. As part of this I have few queries.

1. There is a separate page for Marking an expense report as Receipt Received - Should this page be used only when barcode scanning is in place ? (Navigation - Travel and Expense > Process Expense > Verify Receipts > Receipt Received)

2. Validate Expense Report Receipt page > Is this page also used when barcode scanning in plane ? or this page is used as part of receipt verification approval work flow ? (Navigation - Travel and Expense > Process Expense > Verify Receipts > validate Against Expenses)

3. When an expense report is opened under the Approve Expense report page, we also have a " Receipt Verified" Check box. If we select to use a separate approval step for verifying the expense receipt, can we use this page alone? So that when an expense is submitted, the first level approver will review the attached receipts and approve the expense report by selecting the receipt verified check box at the line level.
