Did this rebuild & verify ever resolve this issue? We are having the same issue and it wasn't a problem in our old QB file from 2021 but it now is in 2022 where our payables are attaching bills to item receipts instead of purchase orders and where we link sales orders to purchase orders. We are about to rebuild and verify this weekend but we have had trouble in the past with other errors popping up after doing that. I would like to know if this worked for you?
