Kanban

Definition : Kanban literally means signboard or billboard in Japanese. It is first implemented at Toyota in 1953 and as per Wikipedia "Kanban maintain inventory levels; a signal is sent to produce and deliver a new shipment as material is consumed. These signals are tracked through the replenishment cycle and bring extraordinary visibility to suppliers and buyers"

As per Oracle White Paper on Kanban, "Kanban Cards are used in a Pull based System. A pull based system is one where inventory items for a particular part or assembly area are replenished as soon as they are needed. When the items are needed, Kanban cards in Oracle Inventory change their Supply Status to Empty, and Inventory generates the Kanban replenishment request automatically."

• Production : This triggers creation of a WIP Job for make item and records are inserted into WIP_JOB_SCHEDULE_INTERFACE
