Use

The KANBAN method for controlling production and material flow is based on a backward chaining of operations in production. Replenishment or production of a material is only triggered when a production level actually requires the material.

In KANBAN, material replenishment can be triggered, for example, by the work center that requires the material sending a card to the vendor responsible for manufacturing the material. This card describes which material is required, the quantity of the material required and where the material is to be delivered. The name KANBAN originally stems from these cards, which are called "kanban" in Japanese.

A further advantage of KANBAN is that the replenishment data can be automatically transmitted. In other words, the bar code reading is enough to transmit the data necessary for procurement and to post goods receipt on receiving the materials.

Using the Internet application component KANBAN, the vendor can request information about empty containers directly over the Internet. This type of replenishment transmission is an alternative to sending the vendor the kanban (i.e. the card) or giving the vendor kanbans for empty containers, if he or she delivers the requested containers. In addition, the vendor can confirm planned deliveries directly over the Internet.

Internet Application Component Type

Business-to-Business

If, as a customer, you want to offer a vendor company the Internet application component KANBAN, you will have the following advantages:

Prerequisites

Authorization/Security

The user, who is to check and refill the product stock, must have authorization for access to the following data:

Authorization object

Description

F_LFA1_APP

Creditor Application authorization

Internet User

To begin the application component in the Internet, the following prerequisites are necessary:

Using transaction SU05 you can create, change and delete passwords for Internet users. To clearly identify the vendor, enter the object type BUS1008 next to the vendor number.

Standard Settings and Pre-assigned Data

In the customer system the data necessary for KANBAN with replenishment strategy "external procurement" must be maintained. This includes control cycles, corresponding replenishment strategies, purchasing info records, contracts or scheduling agreements.

Caution

Control cycles with a replenishment strategy with control type 5 ("Processing via source list") are not included.

Features

Differences with the R/3 Transaction

The Internet application component is a specific view of the kanban board, tailor-made for the vendorís requirements.

The following differences exist between the R/3 standard transaction (kanban board: supply source at vendor) and the Internet application component:

Options for Adjustment

For the Internet application component KANBAN you can expand the data, which is displayed from the control cycle. To do so the standard transaction must be adjusted slightly.

Caution

Every change to R/3 development objects, which are used for the Internet application component, is counted as a modification.

The development objects in the standard system must not be changed. Instead, copy the necessary programs and templates in your own objects in the customer name range.

In the Internet application component there are four tables. In each table there are more program-internal fields available than are displayed in the standard version in the Internet. In order to display further fields in the tables in the Internet application component, you must add the table field corresponding to those table fields already displayed in the step loop of the relevant screen and the relevant template.
