Kanban Replenishment (SAP Library - Warehouse Management Guide)

Kanban Replenishment

Use

The Warehouse Management (WM) system is interfaced to the SAP Production Planning (PP) application component to replenish kanban stock to production supply areas.

Prerequisites

To activate kanban in WM, you need to take the following into consideration in the kanban control cycle:

You need to specify replenishment strategy 0006, which is specifically defined for kanban replenishment from WM.

For the replenishment storage location, you need to enter a WM-relevant storage location. This way, the system knows that it is dealing with a WM-relevant replenishment. In addition to the storage location, you need to enter the WM data to include the warehouse number, storage type as a kanban interface (storage type 150 in the standard system) and the storage bin.

Kanbans are managed in their own kanban storage location that is not WM-relevant. The kanban storage location must be different from the WM storage location from which the replenishment materials are taken. See the figure below.

You define the strategy for the kanban replenishment under Production ® Kanban ® Replenishment strategy ® Define stock transfer strategy in the SAP Implementation Guide.

Activities

To provide kanban replenishment from a WM warehouse to production you

Request the kanban replenishment

Workers must explicitly request kanban replenishment either manually using the PP system or by scanning a bar code.

The system generates 1 transfer requirement with 1 item for each kanban container.

The WM transfer requirement number is noted in the kanban itself. From the kanban, you can display the corresponding transfer requirement (TR). The WM data (storage type, storage bin) defined in the control cycle are copied into the TR.

Process the transfer requirement

You process the TR like any normal TR in WM by creating and confirming a transfer order for it.

Confirm the transfer order

Once you confirm the transfer order (TO), the system updates the kanban in PP by setting the status to "full".

Option: TO Confirmation in Production

As an alternative to confirming the TO, the confirmation of the replenishment can take place in the kanban. If you set the status of the kanban to "full", the system confirms the corresponding TO automatically.

If the TO cannot be processed in the background in WM (for example, zero stock check is required), the system displays an error message and the kanban is marked accordingly in the system. If this occurs, you must confirm the TO manually in WM and correct the kanban in PP.

This kind of discrepancy can be prevented by organizing working procedures in such a manner that it does not occur.

Carry out a stock transfer

After the replenishment has been processed in WM, a stock transfer results between the WM storage location and the kanban storage location. The system can process this stock transfer automatically when the TO is confirmed or you can process it manually by selecting PostChange ® Inventory management ® Stor.loc. to stor.loc. from the WM menu bar.

The Transfer Requirement Header

When you display the transfer requirement header, the following information is of significance:

The requirement number (not to be confused with the transfer requirement number) in the Movement data section consists of the requirement type and a number. The requirement type is J (Kanban/JIT) and the requirement number is the same as the kanban number.

If the kanban indicator is selected, it means that this TR is planned for kanban replenishment.

Destination (interim) storage type: This is taken from the control cycle.

Automatic TO creation: If this indicator is selected, automatic transfer order generation is active. When this transfer requirement is created, the system immediately creates a transfer order for it. (See the field help documentation for this indicator.)
