Backflush for KANBAN Materials

Use

If a production line is the supplier of kanban parts, then the requirement for this production line is created by the kanban signal. The kanban signal creates either a run schedule quantity or manual kanbans as a replenishment element. (For more information, refer to the SAP Document, PP KANBAN, sections Replenishment With Run Schedule Quantities and Replenishment With Manual KANBAN.)

Once produced, the kanban materials are backflushed using the function described here.

Integration

This function is integrated both in the Repetitive Manufacturing menu and in the KANBAN menu.

Prerequisites

To be able to backflush a material procured using KANBAN, you must maintain the kanban master data, such as the control cycle or the supply area. For more information, see also KANBAN Master Data.

Features

As the run schedule quantities created in KANBAN are not reduced in the normal backflush function, a special backflush function is supported in Repetitive Manufacturing.

The functions of the final backflush for KANBAN correspond to the standard Repetitive Manufacturing functions:

The goods receipt is posted for the backflushed material.

The current BOM is exploded.

The goods issue for the components calculated in the BOM explosion are backflushed.
The production quantities are reduced. That is, the planned orders are reduced according to the logic defined in Customizing for Repetitive Manufacturing.

The actual costs are posted to the product cost collector.

If KANBAN with MRP is carried out, the system backflushes and reduces the run schedule quantities with reference to the kanban.
