Why doesn't my sales document line item doesn't show up in Inventory Lookup?

If an item you are searching for does not appear in the search results, there are a couple of potential reasons.  First, in the sales inventory search screen, take a look at the checkboxes in the top right to ensure that only the boxes you need are checked.  For example, if the checkbox for Match Beginning is selected and the text entered is not the beginning of the item number, then your desired item will not be listed.  Search Previously Purchased can also lead to not finding the desired item.  Another important piece is to ensure that the item is not set as Discontinued in Dynamics GP.  SalesPad will not display items that are discontinued and have no available quantity.
