Coexistence Mode for Expenses

Summary

Coexistence Mode for Expenses scenario: create Expenses reports in a third party system, import them in Oracle Expenses (inbound integration) and later process them in Payables

Hi All,
we are in the following scenario: we implemented HCM (Global Human Resources) and Financials (General Ledger, Payables, Receivables), but we didn't implement Expenses and as of now we are not going to implement it because each country involved in the project uses its own local Expenses provider. On the other side, we need to process Expense Reimbursement through Oracle Payables.
As per MOS Doc ID 1613254.1, in order to pay an employee, Fusion doesn't require him to be an employee, but it requires using Expenses module. If we are not implementing Expenses modules as a master (i.e. Employees will not fill out expenses reports on Fusion), does Expenses support a "Cohexistence Mode" allowing the import of expense reports from an externarl system?
