The posting controls we set up are IP16 and IP18. We set up IP16 with the Liability (AP)and IP18 with the Prepaid account. When we ran through a full test the of the Payment Schedule process beginning to end of paying the down payment, the prepaid account was zero and the down payment ended up in the liability account. This leads me to believe that I might have the posting controls set up backwards. How does everyone else have these two posting controls set up?
