This mode works for many of the other picking strategies, and not just for the Sales Pick to Pick Slip option. Typically, a picker can be assigned with several picking slips for different customers, but with the same stock codes (products) on them. The picking screen then directs the picker through the warehouse in a single wave, but the screen jumps between the pick slip lines in the order of the picker movement. The picker will have completed all assigned pick slips by the time they end their picking cycle. This works well with picking cards with levels or “pigeonholes” where each pick slip is placed.
