Progress Billing

SUGGESTED

A progress bill was created, and later a new budget/proposal was created and exported for this job.  In an attempt to reinvoice using the new budget/proposal, the payment on app 1 was voided and the AR invoice (3-2) was voided in error.  When I go to start a new progress bill with the new proposal, Sage won't allow me to save since app 1 is still in a closed status ("Unable to void current application; invoice is paid or void).  What is the best way to correct this so a new progress bill can be created?
