Ok, here is what I found. I closed out the periods from 5/10 all the way to current (7/15), and it removed the new PO's I created earlier today, but the ones that migrated over prior to the history files being created are still in PO Entry. So it appears to close out new ones, but not the old ones (typical this will only work going forward response). *sigh* So now I just need to figure out a way to mass delete the PO's in PO Entry (several thousand). Other than exporting and reimporting, and thoughts?
