Let's walk through a scenario that can occur and lead to 'lost bikes' ( an item you can't find in the system)
You have a set of Bianchi Kuma Mountain bikes:
so you have 3 Items (and an operational capacity of 3)
But then you start deleting (suspending your items) by pressing on the red X button to delete
So you end up with this situation:
Please note, you will still have 3 Items - and they will show up if you use the 'view archived' filter:
Next up you delete the product line to which the (now suspended) Items belong:
Please note - you will now have ZERO Items- even if you view archived - because their parent (product line) has been deleted.
This is because we do the Item counting at the Product Line layer of the hierarchy.
Meaning deleted Product Line = invisible Items below.
You have effectively done this removed the branch your hierarchy that made them visible;
So what is the solution?
Even though bikes with deleted parents will become invisible in the Manage page you can still view them via the search page:
In this way, you can visit your archived items by clicking on the rows above - even if the parent is gone.
You can then change it to have a new parent (product line)
