A/P Generation from A/R Credit

We are newly converted from earlier version of JD Edwards to A9.2

Our A/R group has used in the past the A/P Generation program to create A/P Vouchers for  A/R Credits.  Since the upgrade we have created new vouchers but now we are experioencing where it will not give a list of new invoice numbers to create vouchers for.  The joblog doesn't tell much and the programmer here doesn't see anything wrong with it.  Can anyone tell me if they've had this issue and how they fixed it?

Thanks,

Jill Berglund
