Use

You use this function if you carry out your in-house production using production orders. When the demand source (consumer) sets the kanban to "Empty", a production order is created for the supply source (supplier) for the kanban quantity, thus triggering production.

Prerequisites

You have defined the master data, BOM, routing and work center.

If necessary, you have assigned an appropriate production scheduling profile to the material to ensure that the production order is released and printed immediately it is opened. You define this profile in Customizing for production. In Customizing, choose Production → Production Control → Master Data → Define Production Scheduling Profile. Assign the profile to the material in the latter's master record (Work Scheduling data screen 1).

You have defined a production order type. You have defined the following control criteria for the order type used for Kanban:

Scheduling

As a rule, you use forward scheduling when working with Kanban. The production order type for Kanban supplied in the standard SAP system has the key PPK1 and contains all the necessary presettings.

To specify backward scheduling (for event-driven Kanban), enter the standard production order type PP01 .

Automatic routing selection

In the order type, you specify automatic determination of the routing and maintain a selection ID for automatic determination.

You make these settings in Customizing for production orders under Master data → Order → Define Order-Dependent Parameters. These assignments already exist for the standard order types.

In Customizing for Kanban, you have defined a replenishment strategy with control type 3 or 6 and the corresponding production order type (see above). The following are supplied in the standard system:

Replenishment strategy 0003 (forward scheduling) to be used with control type 3.

Replenishment strategy 0006 to be used with control type 6. With this strategy you can combine Kanban processing with Material Requirements Planning (MRP). Planned orders generated via MRP are reduced as a result of the generation of planned orders through setting the status of a kanban to "Empty". In the replenishment strategy, you specify which planned orders are reduced, up to which point in time planned orders are to be taken into account for reduction, and whether a new planned order is created if a run schedule quantity is cancelled.

The advantage of this approach is that you have the option of a preview, you can plan components, and you have up-to-date data available for the kanban calculation.

You have entered this replenishment strategy in the control cycle.

Activities

You set a kanban to "Empty" or generate an event-driven kanban.

The system generates a production order which (depending on the settings in Customizing) is automatically released and printed.

The empty kanban or the information is transported to the supply source.

Once the order has been completed, the supply source confirms the quantity produced. Confirmation and goods receipt can be coupled in Customizing. You have the following options:

Confirmation and goods receipt not coupled. In this case, the confirmation is entered separately to the goods receipt and status change. When a goods receipt takes place, the kanban status is automatically set to "Full" in the background.

Conversely, you should not set the kanban status to "Full", but always enter the confirmation of the order first.This causes the kanban to be set to "Full" automatically. If you do nevertheless manually set the kanban to "Full", this causes the goods receipt to be posted twice – once when the kanban is set to "Full" and again when the order is confirmed.

To avoid this, set the error type ‘E’ for system message CO823 in Customizing under Shop Floor Control → System Modifications → Define Attributes of System Messages → System Messages

As a result of this, the kanban that you manually set to "Full" acquires the status "Error", so that the goods receipt is not posted twice.

Confirmation and goods receipt are coupled. When the confirmation is saved, the system automatically posts the goods receipt and sets the status to "Full" in the background.

If, in this approach, the goods receipt is entered before the confirmation, the system sets the kanban status to "Full" but does not automatically enter the confirmation. If the confirmation is then entered, the system recognizes that the goods receipt has already taken place and does not post a second one.

The costs are posted to the production order.
