Overview:
Our customer required a solution in Oracle Payables for invoicing and paying a high volume of "one-time" payments via an interface. They didn't want the corresponding suppliers created as Suppliers in Payables. Oracle eBusiness Suite standard functionality did not meet requirements for the "One-Time" supplier. The solution was to create a single nominated One-Time supplier and provide actual supplier details (or employee details if paying employees) on the Invoice itself as Descriptive Flexfield data. 
One Time Supplier Process
The downstream impact of this solution meant the following were required to be implemented:
- Invoice Interface (Payables Open Invoice Interface).
- Extension of custom EFT / Check (Cheque) formats.
- Modification (copy and extend) of reports - Preliminary Payment Register, Oustanding Invoices Report, Invoice Register, Void Payment Register, Final Payment Register.
- Custom XML extraction for confirmed/voided payments.
Key Benefits:
- Consolidation of one-time invoice/payments to one supplier means the supplier database is not cluttered with unused suppliers.
- Easy identification and processing of one-time payments.
- Ease of reporting and intelligence on one-time payments.
- All downstream processes are automated/modified to take one-time supplier payments into account.
Key Decisions:
- One time supplier flag on Supplier only for identification of one-time supplier - did not meet fundamental requirements, so modification was needed to meet business requirements.
- Single Supplier and Supplier Site setup for one-time payments.
- Invoice/payment method details recorded in descriptive flexfields (DFF) on each Invoice.
- All downstream reports/extracts modified to cater for one time supplier.
- Reconciliation between source system and Oracle a fundamental requirement.
