One-Card KANBAN / Using a Special Logic for Triggering the Kanban Signal 
Prerequisites
To trigger a kanban signal with a special logic, you must have defined which signal triggers replenishment in the control cycle.
The signals for triggering replenishment include:
Here, replenishment is triggered for kanban A when kanban B is set to IN USE
Here, replenishment is triggered for kanban A when kanban B is set to WAIT.
Here, replenishment is triggered for kanban A when the actual quantity of kanban B reaches or falls below the trigger quantity. In this case, you must have maintained the trigger quantity in the control cycle.
Procedure
To trigger the kanban signal, you can also use the functions that are available in classic KANBAN, for example, you can use a bar code or the kanban board. A replenishment element, however, is only created if you have set the appropriate status in the control cycle.
