Dear Expert-- 

We are trying to accomplish to split the invoice by the suppliers, and internally assigned to the AP specialist by the suppliers, lets say Supplier [A-L] to AP Specialist ‘1’, and Suppliers [M-Z] to AP Specialist ‘2’.

Client requires the Invoices should be Routed/Assigned to the AP Specialists upon Importing the Invoices from the Oracle Imaging solution

It appears, the [Oracle Imaging solution + Fusion/Cloud AP] don’t have the Invoice queuing concept/function/feature, the Only Invoices we can route/assign are the one in ‘Incomplete’ status, even to route those, we have to manually update the each email’s subject line before we forward it for scanning; that’s not practical for even Incomplete invoices.
