 In such an environment, where the production order received form the ERP\MRP software is scheduled using a MES or Kanban and the materials are assigned to the shop floor at the withdrawal from stores, there is no need for using backflushing.The materials are usually issued from the stores to a supermarket on the shop floor without being related to a specific production order but in the amount needed to cover the demand of the already released production orders.This amount is dynamic and we call it "Kanban-quantity".
