Slope uses the term inventory to describe the types of stuff you have to track for a clinical trial or protocol. Things like lab kits, thermal shippers, tubes, bulk supplies, etc... the list goes on. Each of these inventories are made up of individual "units" (e.g. you might have 25 Blood Draw Kits on hand). Slope calls each of these individual "units" an item.
Slope also assigns every item at your site a status. We use that status to help keep track of whether an item is usable or unusable. Items can be assigned to any one of the following states:
Ready - The item is not expired, on-hand, and can be used immediately.
Used - The item has been used and is no longer available.
Expired - The item has expired and is no longer usable.
Damaged - Somehow the item was damaged and it is no longer usable.
Lost - You had this item but can't find it any more. Use this to mark the item as lost, rendering it no longer available.
Returned - You sent this item back to where it came from and it's no longer available.
Disposed - You disposed of this item and it's no longer available.
There's also another state called Expiring, which will activate for an Item that. Expiring items can still be used, but have an expiration date that falls within the next 30 days.
How to update item status
When looking at an inventory (or storage area) detail view, you'll see a list of items within that inventory (or storage area). Here's an example of what that looks like:
Clicking the inline Actions button next to an item in this table will reveal a dropdown with a list of the available transitions you can do for that item:
If any of the transitions are unavailable for the current item's view context, Slope will disable the transition link and show a popup tooltip explaining why the transition cannot be accomplished.
