Cluster picking is piece picking process where the user can pick items for multiple orders at the same time by ‘clustering’ them together into pick clusters while visiting the pick location only once. Typically, this functionality will be used with small order picking or less than case quantities. With the setup of system directed cluster picking you can cluster pick work headers based off a system generated cluster. The system will cluster up picking orders up to the number of positions specified on the cluster profile and allows the user to pick multiple orders at the same time without having to create a cluster manually.
