Status Change/Kanban Signal
Use
The progress of production in KANBAN is controlled by setting the kanban to the appropriate status. By changing the status, both the demand and the supply source are also guaranteed an up-to-date overview of production progress in the kanban board. Usually, only the two statuses, EMPTY and FULL are used. If the material in a kanban is used and a kanban is then set to EMPTY, then replenishment is automatically triggered with this kanban status, i.e. the supply source receives the signal to refill the kanban. When the kanban is returned, full, to the demand source, it is then set to status FULL and goods receipt is posted for the material. As a rule KANBAN is possible with both statuses EMPTY and FULL, and the status changes are made using a bar code and a bar code scanner. The system automatically sends all important information from the demand source to the supply source simply by scanning the bar code.
If additional information is required for a special case, it is also possible to set other statuses:
indicates that the material has been consumed but the supply source should not yet deliver more material. This status is also set when a new kanban is introduced to the control cycle.
indicates that the requested material is currently being produced by the supply source.
indicates that the material is currently on its way to the demand source.
indicates that the demand source is currently withdrawing material.
is set by the system and indicates that the status selected cannot be set successfully.
The first four statuses only make sense if you use the kanban board. These statuses are actually set in the kanban board and inform you exactly how far production has progressed.
Features
The following statuses are available:
The system sets the status WAIT in the following instances:
The status WAIT can also be given by the demand source in the kanban board for information purposes if certain kanbans are not to be refilled immediately. Please also see
When the kanban is empty, the demand source sets the status to EMPTY. Depending on the replenishment strategy, setting the status to EMPTY automatically triggers replenishment.
The statuses IN PROCESS and IN TRANSIT are set by the supply source to inform the demand source that the kanbans are either being processed or they have already been sent and are currently in transit. (These two statuses can only be set in the kanban board.)
The demand source sets the status to FULL on receipt of the full kanban or when posting the goods receipt for the kanban. Exception:
The status IN USE is set by the demand source to inform the supply source which kanbans are currently being emptied. (This status can only be set in the kanban board.)
The status ERROR is set by the system if an error occurs when processing a kanban. An error may occur if a kanban is set to EMPTY and a purchase order is to be created simultaneously. If the vendor desired is locked or invalid, it does not make sense to deal with this situation online. The kanban is set to ERROR and is assigned an appropriate error message.
If you have defined in Customizing for KANBAN that an error message is issued when a certain error occurs, then the kanban is not set to ERROR.
Statuses 2 and 5 are mandatory statuses, used to control the KANBAN procedure. Statuses 1, 3, 4 and 6 are all optional statuses, used for information purposes.
The status of each kanban is displayed in the kanban board, each status having a different color. A legend is available so that you can easily see what each color represents (Kanban board
® Display legend).The sequence of the status changes is displayed in the following graphic:
