On Friday, we had about 40 PO's go into an Unreleased status after previously being EDI'd, received, and invoiced - dating from June 2016-August 2016. The interesting thing is that all of these PO's are for the same vendor and they all have one or more items that have had cost messages since the invoice came through but haven't been resolved, or were just resolved yesterday 9/6. So none of these invoices have been paid (or else the PO's would have closed at month end).
Has anyone else ever encountered this? The buyer said they all showed up on PO20 around the same time, making us believe no one person did this.
