Lesson Overview
Reduced posting effort is an important characteristic of kanban processing. This lesson illustrates which posting occurs during which kanban process.
Lesson Objectives
After completing this lesson, you will be able to:
• Perform a kanban status change with different applications
Business Example
In your production sequence, you want to simplify certain processes and use streamlined concepts such as kanban. You want to inform yourself about the technical application and the associated background processes of kanban.
Figure 16: KANBAN Status Sequence
All KANBAN operations, such as material receipts or material consumption are represented by status changes.
If the material in a kanban is used up, the employee sets the status of the kanban to empty. This kanban status usually also automatically triggers replenishment, that is, the supply source receives the signal to refill the kanban. When the replenished kanban returns to the demand source, the employee at the demand source sets the kanban to status Full. These two statuses are generally sufficient to control the

Figure 17: Goods Receipt/Goods Issue -vs.- Kanban Status
The goods issue confirmation results indirectly and is therefore separate from the immediate number of components in the kanban container. Inventory management only takes place at the level of the production storage location (not at the level of the kanban container).
The kanban is set to empty if the relevant material has been consumed (optical control by worker). This operation is based only on the physical stock and is completely independent of any stock posting at storage location level.
Figure 18: Setting the Kanban to EMPTY
The progress of production in KANBAN is controlled by setting the kanban to the appropriate status. Usually, only the Empty and Full statuses are used.
If the demand source sets the status to Empty, the system creates a replenishment element, instructing the material supply source to deliver.
Setting the status of a kanban to Empty does not lead to a goods issue posting.
In kanban, goods issues are typically backflushed during the confirmation of the order above it (or during the manual goods issue posting of the order above it).
You can set the status to Empty by scanning a bar code on the kanban card. To do this, you scan the bar code using a standard bar code scanner in the transaction Kanban Signal → Bar code. You can also set the status to Empty using the Manual Kanban Signal transaction or using the KANBAN board.
SCM350 Lesson: Status Change and System Activities
Figure 19: Setting Kanban to FULL
If the demand source sets the status to Full, the system automatically posts the goods receipt for the material with reference to the procurement element.
You can set the status to Full by scanning a bar code on the kanban card. To do this, you scan the bar code using a standard bar code scanner in the transaction Kanban Signal → Bar code. You can also set the status to Full using the Manual Kanban Signal transaction or using the kanban board.
Figure 20: Posting Goods Receipt Manually
You can also post the goods receipt manually in Inventory Management. The goods receipt posting in Inventory Management automatically changes the status of the kanban to Full (if you have not set the separate goods receipt indicator in the control cycle).
Figure 21: Status Sequence - All Possibilities
If there is additional information for certain processes, there will be an additional status alongside statuses Empty and Full. In addition, the status Wait is set in the following cases:
• When a new kanban is included in the control cycle, it is given the status Wait. The demand source can then set it to Empty.
• If a kanban has been locked and is then set to Empty.
• The status Wait can also be specified by the demand source in the kanban board for information purposes if certain kanbans are not to be refilled immediately.
• If the Independent Supply Source/Separation of Status Change and Replenishment has been defined for a control cycle. As a result, the kanban signal from the demand source does not trigger replenishment. Instead, the kanban is given the status Wait until the supply source triggers replenishment.
In Process indicates that the requested material is currently being produced by the supply source.
In Transit indicates that the material is currently on its way to the demand source.
In Use indicates that the demand source is currently withdrawing the material.
SCM350 Lesson: Status Change and System Activities
Error is set by the system and indicates that the status selected cannot be set successfully.
The statuses Wait, In Process, In Transit and In Use are only of use when you work with the kanban board. These statuses are actually set in the kanban board and inform you exactly how far production has progressed.
Signal locking time in KANBAN Customizing for replenishment strategies: The signal locking time defines a period (in minutes) in which the kanban signal is locked after the signal is triggered. If you re-trigger the kanban signal within this period, the system will not change the status. This guarantees that a kanban cannot be set to FULL and then inadvertently set to EMPTY again by a second signal.
