Purpose

You can perform the automatic kanban calculation by choosing   Control Cycle   Kanban Calculation   Create Proposal   from the Kanban menu and selecting the relevant control cycles there. See also: Carry Out Automatic Kanban Calculation .

The system then calculates one of the following two magnitudes on the basis of existing requirements and your specified calculation parameters:

  • Number of kanban containers (cards) that are to circulate in a control cycle

  • Quantity of material to be procured per kanban container

With the number of kanban containers and the quantity of material per container, the material circulation and the stock of material in the control cycle are defined.

To ensure the lowest possible stock of material while simultaneously achieving a secure material supply, the setting of these two values must be optimized. Because the requirement situation often fluctuates considerably in many industries, it is necessary to check and adjust these values with the automatic kanban calculation on a regular basis

Prerequisites

The following prerequisites must be fulfilled for automatic kanban calculation:

  • You have checked/adjusted the calculation parameters in the calculation profile in Customizing for Kanban.To do this, in Customizing, choose   Production   Kanban   Automatic Kanban Calculation and Scheduling   Define Calculation Profiles   .

  • You have maintained the standard values for the automatic kanban calculation in the control cycle on the Kanban Calculation tab page. See also: Defining Automatic Kanban Calculation in the Control Cycle .

  • If necessary, you have specified which requirement types are to be taken into account in the kanban calculation in addition to the dependent requirements. See also: Taking Further Requirement Types into Account

  • If necessary, you have maintained the extended dependent requirement selection in the control cycle. See also: Extended Dependent Requirement Selection

Process Flow

  1. The system determines the relevant requirements on the basis of the results of the MRP run or long-term planning. If you have defined further requirement type, the system can also take these into account. See also: Determination of Requirements .

    In addition, the system can smooth the determined requirements in accordance with the settings in the calculation profile.

  2. In the kanban calculation, you can work with full-day or sub-day replenishment lead times. See also: Calculating the Replenishment Lead Time and Converting the Requirements .

  3. The system calculates the number of kanban containers/kanban quantity for the replenishment lead time using a formula. See also: Calculating the Number of Kanbans/Kanban Quantity .

  4. If you have additionally set calculation parameters, the system also calculates the necessary number of kanban containers/the kanban quantity for each of these parameters.

  5. If you have made the setting for the capacity-based kanban calculation, in the case of in-house production, the system can also take the capacity of critical work centers into account. See also: Capacity-Based Kanban Calculation in Case of In-House Production .
