Why Stocks in In-Process are reflecting in Usable

Q: Why the stock status is still reflecting usable when it’s in Picking state? It should be removed from usable to In Process status.

A: The order is in In Picking state as it is still under Picker Assigned state, once the picking is completed, the order will be moved to  In Process state and after Packing is completed, usable stock will be deducted.
