I have a question about the PPA (PO Price Adjustment) invoices which get created when we run Create Adjusting documents in Payables Program. Is there a setting/profile option/way thru which we can only allow this program to adjust existing invoices (to relieve IPV and Accrual balances) but not create PPV invoices which can increase/decrease liability.

We also use Retro pricing. Our business gets invoices from supplier as per new/updated price which they enter and pay.
