For customers with item elevators it would be quite more efficent if it was possible to split pick work for defined zones. Main picking rout will be frozen untill the pick work for the defined zones are done and placed to a staging location. The staging location will then be a part of main picking rout.

A good scenario would be a sales order with multiple items where some items is to be picked from a elevator and some from other zones.
Work splits out the pick line from the elevator and freezes the rest of work.
Elevator picking lines are picked in cluster pick and is placed to staging location, e.g. one location pr. salesorder.
When the cluster pick is done and placed on the staging location, main pick is released. The staging location will then be a part of the main picking rout and instead of "picking" every item the picker will scan a licensplate and the location. All items in this location is then picked.

This is a efficient way to handle this. It is not possible to set this up as a replenishment from elevator, i have tried without success. I have seen many other systems beeing able to use this logic and pick this way and i would like to see this function in D365FO for WHS
