Accept Kanban Calculations

Explanation

Use this activity to replace the existing or current Kanban quantities for a Kanban circuit with newly recalculated quantities. Once you accept the changes, the new quantities are ready for implementation on the shop floor and the system adds or subtracts the appropriate number of Kanban cards. The status of the circuit is Recalculated before the changes are accepted. After acceptance, you can change the status as adjustments are made to the Kanbans. Acceptance of the new quantities marks the transition from the Kanban Planning to the Kanban Execution process.

Kanban cards with the New and In Circulation status can be changed to the Surplus status and vice versa. Surplus cards have restricted usage. However, they are counted as usable when calculating the number of new cards that need to be created. Only Printed Kanban cards that have their quantity recalculated will be made Obsolete after accepting the recalculation. Not Printed cards will remain in the same status as before the calculation. The other way you can change the status of the cards to Obsolete is by manually changing their status.

If new Kanban cards are needed when performing calculations, they should be created based on the following formula :

New Kanban Cards = Kanban Cards Required - (New + In Circulation + Surplus Kanban Cards)    

Prerequisites

This activity requires that the status of the Kanban circuit be Recalculated and that the new Kanban quantities differ from the current quantities.

System Effects

• The system saves the current Kanban quantities to the history record and accepts the newly recalculated quantities for use in the production environment. 
• If either the quantity per Kanban, lot size or reorder point value has changed, the system will create new cards or set the status of the existing cards to Surplus.  
• The system will generate new cards if the number of Kanbans has increased or if the Obsolete cards must be replaced and the Surplus cards are insufficient to meet this demand. 
• If there are too many cards in the circuit, the excess cards that are in the New and In Circulation status, will receive the Surplus status. If necessary, a message will be displayed informing you of any other cards that have to be subtracted, by displaying a negative value in the Cards to Add/Subtract field on the Cards tab of the Kanban Circuit window.

Procedure

Right-click and then click Accept Calculations, then click OK. The status of the Kanban circuit changes to Active, and the newly recalculated Kanban quantities replace the current quantities.
