Demand Schedule Generation for Kanban Management

When material requirements planning (MRP) generation is complete, the planner runs the demand schedule extraction to generate the supplier item demand schedule. The system processes the MRP messages that it generates for both kanban-controlled and non-kanban items.

Before you can successfully use supplier release scheduling (SRS) for kanban-controlled items, you must define the demand by running the MPS Regeneration program (R3482) or inputting a manual (ad hoc) release schedule.

Note: You do not need to create a blanket order for kanban-controlled items. You do not need to set up the supplier release master record in the Supplier Schedule Master Revisions program (P4321) because the kanban master identifies the supplier for the kanban-controlled item.

When SRS is set up, the system generates the demand schedule in the Vendor Schedule Quantity table (F3430).

Each time you generate the demand schedule, the system verifies whether an item is kanban-controlled, but it does not generate releases or purchase orders (neither blanket nor non-blanket, for kanban-controlled items), even when a supplier is commitment for the item.

The purchase order is released at the time of kanban check-out. If you set up an outbound transaction (EDI 862), the system publishes it.

The Supplier Release Schedule Generation program (R34410) ignores release generation for kanban-controlled items.

You can set a processing option that enables you to publish the demand schedule in the form of an outbound transaction (EDI 830).
