In KANBAN production control, you have two options for organizing replenishment:

• Replenishment is only triggered by the kanban signal. Materials for which replenishment is only triggered by the kanban signal are not planned in the planning run. However, you can include these materials in long-term planning.
• The materials are planned in the planning run and corresponding procurement proposals are created. These procurement proposals do not directly trigger replenishment but provide a preview of future consumption. In this process, replenishment is also triggered by the kanban signal.

You can use both options for organizing replenishment in the classic KANBAN procedure and in the other KANBAN procedures.
