Partial Payments

This is a discussion on Partial Payments within the Commerce server forums in Microsoft Tools category; Hi I am trying to post partial payments to an order e.g. someone comes to the office and pays 1/2 with a cash payment and the other 1/2 on credit. I have discovered that commerce wont let me post two partial payments with the same credit card. I would think this would be a fairly common scenario e.g. someone pays a deposit on the phone then clears the balance when the item arrives. The message that I receive is "A similar payment already exists in the collection"...
