The current way to check if pick bin needs to be replenished, is too complicated and not useful.
If an item is missing or not enough qty in a pick bin, you need to calculate manually the bin replenishment.
This should be calculated automatically when creating picks. In the needed qty in the pick bin is not enough, D365 BC should generate a bin replenishment so all needed quantities are available during picking, and not stop the picking and waiting for replenishment.
The bin replenishement instruction should be assigned to another warehouse employee or added on the pick order but before the pick action.
