Returns under Purchase order enhancements

[swabunn]

Great Plains 8.00
sql server 2003

we are using purchase order enhancement for purchase and inventory returns. I want to see the linked documents to the returns. In the return transactions inquiry zoom window, I can see return no and receipt number but I don't see the table name for this window under the resource window or tables for purchase returns linked to receipts number.

Thanks
