If the demand source empties the kanban, no replenishment elements are created. You use this type of replenishment if your production is controlled purely by the kanban card or the kanban board and not by the planned orders created by the system.
If you want to work with the manual KANBAN procedure, you must provide the material with a repetitive manufacturing profile in the material master record which allows settlement via cost collector. In the standard system, the repetitive manufacturing profile 0005 is used. This profile contains the parameters for this replenishment strategy, in particular for the determination of the cost collector. For more information on the cost collector and the repetitive manufacturing profile, seeCost Accounting for KANBAN.
As soon as the kanban is empty, this information is conveyed to the source. The supply source receives the information either via the kanban (card) or via the kanban board. The supply source produces the kanban quantity. If the kanban board is in use, the supply source can set the kanban status to IN PROCESS or IN TRANSIT which informs the demand source of production progress.
Backflushing is carried out using the backflush transaction or by setting the kanban status to FULL. The backflush transaction is linked to the goods receipt posting of the manufactured product and the goods issue posting for the components.
If the status is set to FULL or the backflush transaction is posted without component processing, then the system explodes the current BOM. If you want to change components, you should work with the backflush transaction where it is possible to branch into the component processing functions.
The costs incurred in production are posted to the cost collector. To determine the cost collector see Product Cost Collectors.
Independent Supply Source
This is only used for information purposes, as no replenishment element is created.
Separate Goods Receipt
During the backflush, the goods receipt is posted, but the kanban status is not set to FULL. If a goods receipt is posted before the backflush, the system does not automatically set the kanban status to FULL.
In a separate goods receipt, only the backflush increases the kanban quantity and not the status change to FULL. Therefore, if the backflush is carried out, the kanban quantity is refilled, even if at this point in time, the kanban status has not been set to FULL. (This change is displayed in the kanban board by a + in the kanban status.) If the kanban status is set to FULL before the backflush has been carried out, the kanban quantity remains at zero until the backflush has been saved.
It is not possible to reset the kanban status to EMPTY before the backflush has been carried out.
