If you subrent gear, there's one number worth understanding properly: Qty Reserved on your Gear Order. Once you know what it's counting, the rest of the Purchase Order makes sense.
The Short Version
A Purchase Order adds gear to your available pool for the dates it covers. Because that gear is genuinely available, your Gear Order can reserve it — so Qty Reserved includes what you're subrenting.
If you need five, own three, and subrent two, Qty Reserved shows five. Your order is covered, and the number says so.
That's specifically on a Gear Order in a status that reserves gear. If the Gear Order isn't reserving gear yet, Qty Reserved stays at 0 and the subrented gear shows in Qty Available instead, it's held for that order, so other orders won't see it in their Qty Available. If you've used LASSO for a while, this is a change: Qty Reserved used to leave subrented gear out. Now it counts it, because the Purchase Order adds that gear to your available stock.
The Two Columns to Watch
Qty Reserved: how much of the line is covered, including anything arriving on a Purchase Order.
PO/TO Qty or Qty Subrented: how much of that is coming from a Purchase Order or Transfer Order.
PO/TO Qty: for customers with multiple warehouses
Qty Subrented: for customers with one warehouse
A blue quantity means a Purchase Order or Transfer Order covers the shortage, and red means it's still short. Click the underlined PO/TO number to open the line's cost panel, which lists its Sub Rentals and Transfer Orders. Click a Purchase Order there to open it in a new tab.
Follow It on the Item Schedule
The Item Schedule is the clearest picture of what a subrental is doing. Open any product and you'll see availability rise for the dates your Purchase Order covers, then drop back when the gear goes out of service.
Underneath, Inventory Changes lists each Purchase Order moving that number, with its vendor and PO number, so you can tell at a glance which subrental is covering which week. Incoming rows show only what's still to arrive, so they drop off as you receive. Subrentals are tagged LTS In (last in) and LTS Out (last out), and purchases are tagged EPO In.
The Dates Set the Window
Availability doesn't follow the delivery date. It follows the In Service and Out of Service dates on your Purchase Order, falling back to Delivery and Return if you haven't set them.
So if your show needs gear before the In Service date, or after Out of Service, you'll still see a shortage- the gear exists, but not yet, or not any more.
Your Subrental Stays Earmarked
A Purchase Order line tied to a Gear Order line holds that gear for the line during the show's dates. Other orders can't reserve it then, even though it's sitting in your availability. If the Purchase Order brings in more than the line needs, the extra joins your general pool.
Equipment purchases work differently: they raise your availability and leave it there, because nothing is going back.
Common Questions
Why did my Qty Reserved go up?
A Purchase Order is covering it. Check PO/TO Qty on the same line to see how much is coming from a vendor.
Is my show actually covered?
It's covered for the dates the Purchase Order covers. Check those dates against your prep and return if you're unsure.
Where do I see how much is subrented?
The PO/TO Qty column, next to Qty Reserved.
