Creating/Changing Control Cycle for Classic KANBAN
Purpose
This process describes which parameters you need to enter for a control cycle with classic KANBAN.
Process Flow
To create a control cycle for classic KANBAN, proceed as follows:
The system displays the initial screen for maintaining the control cycle.
The system now displays the data screen for maintaining the control cycle.
In the control cycle you define how replenishment between the supply source and the demand source is to be organized.
For further information see also Defining the Replenishment Strategy in the Control Cycle.
For kanban circulation you need to define the following:
The number of kanbans as well as the kanban quantity is based on the following criteria:
This is represented in the following formula:
You can also use the functions available in the automatic kanban calculation to determine the number of kanbans or the kanban quantity. For further information see also Defining the Automatic Kanban Calculation in the Control Cycle .
If the containers have their own material master records, you can enter the material number of the container for the kanbans. A new material type is provided for the kanban containers (CONT). Using the material type CONT, means that it is simpler to maintain the material master record (you only have to maintain engineering/design data). However, you can also use other material types to created kanban containers.
You can enter a limit that specifies the maximum number of containers that are allowed to be empty at one time for the supply source view of the kanban board. This limit is only used for information purposes and evaluation. If the number of empty containers exceeds this limit, the system displays an exclamation mark in the line of the appropriate control cycle in the supply source view of the kanban board.
You define whether or not the kanbans are to be printed and which event is to trigger the printout. You also specify the output device. For further information see Printing and Circulating Kanbans .
If necessary, you can delete or lock kanbans in the control cycle. You lock a kanban, for example, if it is not to be used for a certain length of time as consumption within the control cycle has fallen.
You can only delete a kanban if it has no further replenishment elements for which goods receipt still has to be posted. All kanbans that do not have the status WAIT, must be locked before they can be deleted.
If the status of a locked kanban is set to EMPTY, the system automatically changes the status to WAIT. A locked kanban cannot be replenished.
To lock or delete a kanban, choose Goto ® Kanban.
A dialog box appears displaying the following information:
To lock kanbans, select the checkbox of the appropriate kanban(s) in the Lock column.
To delete kanbans, select the checkbox of the appropriate kanban(s) in the Delete column.
If you want the delivery to be made directly to the production line, you can specify a precise delivery address indicating the supply area data.
To do this select Goto ® Delivery address.
The plant address is already complete. Here, you can also enter the information required for the supply area.
Further Control Data
In addition, you can control the separation of the goods receipt from the status change with the field Separate GR (for further information read Separating the Status Change from the GR Posting). With the field Independent supply source you can control whether the supply source determines the time of replenishment and whether the replenishment element has the status "independent supply source". (See also: Independent Supply Source/Separation of Status Change and Replenishment).
You can assign a status sequence to the control cycle in the Status sequence field. This defines the order in which the statuses are set. It also specifies whether certain statuses are mandatory, whether some are optional, or whether some statuses are not allowed. For example, you can define that the statuses, IN PROCESS and IN TRANSIT have to be set after each other, but that the status IN USE is not allowed. You define the status sequence in Customizing for KANBAN. For further information on status see Status Change/Kanban Signal and Status Sequence .
In the one-card KANBAN system, you must define a special logic for triggering the kanban signal. These logics are defined in the field Trigger replenishment. See also: One-Card KANBAN and One-Card KANBAN/Using a Special Logic for Triggering the Kanban Signal . If you do not want the system to trigger replenishment until a trigger quantity has been reached, you must also enter this quantity in the Trigger quantity field.
You can also change the supply area in an existing control cycle, if the new supply area points to the same location as the old one.
