Background: Vendor Service Inquiry
Use the Vendor Service Inquiry (VSI) program to display invoice information, invoice history, and AP aging information for a vendor. See Road Map for work flow.
To see vendors paid with a credit card, run the AP Payment Method Codes Maintenance (TAPM) program. For example, if the AP Payment Method Codes Maintenance program shows the VISA payment method has a vendor number of VISA, enter VISA in the Vendor Service Inquiry (VSI) program to display the Orig inv button. You use this button to see purchasing details for vendors paid with a credit card.
