In the Bin Contents calculation code there is a calculation function for Qty Available to Pick. This excludes inventory in dedicated bins , bins blocked for movement (outbound / All) and blocked lots or serial numbers.

This is a very valuable field, much more valuable than the Qty Available to Take, at least when looking at qty for picking.

Please make this filed available on the Bin Contents page (we are doing it for customers now that I know it exists as it is what they are usually looking for when consulting the bin contents.)
