Identification of Employee reiumbursements and vendor Payments

Hi,

We are making the payments to employee reimbursement  and vendor payments through Payables module(11i version).

We can identify the invoices / payments with following conditions.

If Employee reimbursement - vendor_type_lookup_code as "EMPLOYEE" in PO_VENODRS table

If Vendor Payment - Vendor_type_lookup_code as "SUPPLIER" in PO_VENDORS table.

In some scenarios, Employee provided the service to Organization(i.e employee as vendor). Now how to record those invoices whenever the employee as vendor without creation of any additional DFF.

Regards,

Madhu
