clearing prepayment to partial receipt

[lsmith7972]

I accept prepayments and I list per the instruction book so it appears on the sales order receipts function as the negative amount referenced against my sales order. I have partially shipped against the sales order. How do I show payment for this partial shipment without causing the entire prepayment to disappear?

Select Reciepts and apply a portion of the prepayment to the now open partial shipped Sales Order / Invoice. This will clear the Invoice and will leave the balance of the prepayment as an open credit.
