It is suggested that in item generic search, we have the option to show item quantity per global setup. It is suggested that, we need to allow user to press a flag that only show those item quantity is greater than zero so customer service rep can focus on those item that we have on-stock.

Currently, the bottom line of the item generic search can as following:
Up, Dn, PgDn, PgUp, F4=Detail
Up, Dn, PgDn, PgUp, RETURN To Select
Up, Dn, PgDn, PgUp, F4=Detail F5=Wish List
Up, Dn, PgDn, PgUp, F1/F2=Next/Prev Loc F3=Setup F4=Detail
Up Dn PgUp/Dn F1/F2=Next/Prev Loc F3=Setup F4-Detail F5=Wish

We can modify to allow F7 key which is a toggle key to display between showing Qty > 0 only, or show all items. See below:
Up, Dn, PgDn, PgUp, F4=Detail, F7=Qty>0
Up, Dn, PgDn, PgUp, F4=Detail, F7=QtyAll
Up, Dn, PgDn, PgUp, RETURN To Select,F7=Qty>0
Up, Dn, PgDn, PgUp, RETURN To Select,F7=QtyAll
Up, Dn, PgDn, PgUp, F4=Detail, F5=Wish List, F7=Qty>0
Up, Dn, PgDn, PgUp, F4=Detail, F5=Wish List, F7=QtyAll
Up,Dn,PD,PU,F1/F2=Next/Prev Loc,F3=Setup,F4=Detail,F7=Qty>0
Up,Dn,PD,PU,F1/F2=Next/Prev Loc,F3=Setup,F4=Detail,F7=QtyAll
F1/F2=Next/Prev Loc,F3=Setup,F4-Detail,F5=Wish,F7=Qty>0
F1/F2=Next/Prev Loc,F3=Setup,F4-Detail,F5=Wish,F7=QtyAll

The F7 key will only be available if the Global Setup -> Dist -> I/M Global Control, field "4. Item Generic Search With Avail/Excess Qty" = "Y".

The Qty to filter depend on whether we are displaying Item Qty Avail, Location Qty Avail, or Excess Qty (which is base on another Global Setup Flag).

Special logic need to considerate when user press F5, there may not be any item qualify to display in some situation, and the program still need to handle it gracefully (maybe reverse the toggle key back after showing no item to display, because it obviously make no sense to display no item in generic search screen). Also, the search show base on the current pointer of item, not a starting over search when F5 key is pressed.
