If sales orders are loaded with lines from multiple warehouses the releasing process will create a linked picking slip for each warehouse with a set warehouse being the master. Each picking slip is picked independently and then delivered to a joint dispatch checkout area.
Orders can also be split by warehouse area if the distribution center is large, and we have pickers assigned to areas.
Pick line limits can be set to never allow a packing slip to include more than a maximum number of lines. This can be set to ensure that we balance the load in the warehouse.
