Click Sequence:- Imported Checking Transactions- Viewed Checking Account- Right Clicked a payment- Clicked Assign As Payment- Process Payment Window Opens- BUT only allows choosing Customer- Can not choose Vendor

Reference Manual 7.1 

There is an alternative way of assigning a payment to (one or more) bills where the payment transaction already exists, say in the case where transactions are imported from a bank.

This can best be done starting from the asset account register holding the imported payment transaction (like your bank account). In that account, select the payment, right-click (control-click for Mac OS X) and choose Assign as payment.... The payment window will pop-up, partly filled in with the information from the transaction. Fill in the missing information like the proper vendor and bill to complete the payment.
