The system functions in this manner on GP 2015, GP 2016 and GP 2018. When the option to Allow Duplicate Invoices Per Creditor/Vendor in Payables Setup is marked, the Edit Payables Transaction document number lookup pulls in the 'first' invoice for editing regardless of which voucher is selected. Here is an example: Voucher 001 is an Invoice for $120 = Document Number TEST Voucher 002 is an Invoice for $60 = Document Number TEST If the user selects the $60 invoice using the lookup, the $120 invoice is pulled in for editing. Additionally, using the navigation arrows to try to scroll to the other document does not select it either. Only the "first" of the Invoices with a duplicate Document Number can be selected. Would like to see the system allow you to select for editing and look at more than just Doc Number in this window. Thanks
