If you want to trigger replenishment using KANBAN, the system creates the replenishment element (such as a planned order) when the status is set to EMPTY. If necessary, you can separate these two operations.

If you have set the system so that they are separated, the supply source triggers replenishment and not the demand source. The demand source sets the kanban to EMPTY. However, no replenishment element is created and the system automatically sets the kanban to status WAIT. The supply source then sets these kanbans to EMPTY in the kanban board which creates the replenishment element. The independent supply source thus determines the time of replenishment itself.

The replenishment strategy is determined in the control cycle. The control cycle is also assigned the indicator "independent supply source".
