Setting up On Account Payment

• For a check that is permanently uncollectible with the amount of the returned payment not included in control totals, we recommend that you:

1. Unpost the original payment.
2. Reapply the original payment as an on-account on the payment worksheet, optionally using an entry reason to indicate why this action was taken.
3. Write off the on-account on the maintenance worksheet, optionally using an entry code to indicate why this action was taken. 

We are trying to implement the above for NSF.  I thought I set everything up but the payment worksheet still shows as Partially Paid.

What do i need to set up to get an OAP to post and be available for a worksheet?
