I have just tried the new system directed cluster picking functionality and it is a big step forward, however you still need to scan all the slot license plates at the start of the pick. Generally cluster picking is performed in sectioned trolleys, which could have each slot bar-coded with a License plate. My proposal is that the concept of a trolley is introduced. The trolley will have a number of slots, each of which is associated with the relevant license plate. System directed cluster picking could then prompt the user the scan a Trolley ID and then automatically associate the license plate for the relevant slot to the Target license plate for the slot. Hence the picker would need to perform one scan instead of up to 30 prior to starting the pick.
