On the ‘Dashboard’ there is an indicator known as a ‘Late PO’ - this shows the number of POs that should have been received already, but have not. Clicking on it will bring up the list.
In general, the PO table filtering will help you with all this. For example, to bring up a list of items that need to be there in the next five days:
1) Open the ‘Purchase Orders’ screen and view it by items.
2) Choose the statuses: ‘New’, ‘Ordered’, and ‘Shipped’.
3) Choose your ‘Expected’ date and mark it as 5 days from today.
4) Click on ‘Search’.
