The available to take on the bin contents really should match the available to pick calculation when generating a pick, Or maybe add a new field Available to Pick?

Currently it does not exclude lots blocked on the lot information or even items that are blocked.

This is really confusing as the the user sees 1000 available to take and then tries to create a pick and either get nothing to handle or a smaller number when some of the inventory is on a blocked lot.

This is a pretty simple change and could also include a new field blocked inventory in the bin.
