Use this form to calculate the kanban quantities that are used in kanban rules. The calculation determines the average projected demand that occurs during the defined calculation period. The calculation is based on the known demand from forecasts, open orders, past orders, and historic consumption.
Note
Before you can use this form, a kanban quantity calculation policy must be created. See Kanban quantity calculation policies (form) for more information.
Make sure that the master plan that is associated with the calculation policy is up to date.
To calculate kanban quantities, follow these steps:
Create a kanban quantity calculation, and define the date parameters that are used in the calculation.
On the Kanban quantity proposals tab, click Generate to generate calculation lines for the items that are replenished by the associated kanban rules. Each kanban rule generates one calculation line that is included in the calculation. You can also manually add calculation lines to the calculation and remove calculation lines from the calculation, either before or after you perform the calculation.
On the Kanban quantity proposals tab, click Calculate to calculate the kanban quantities for each proposal line. The proposal lines are calculated based on the kanban quantity calculation policy that is selected and the date parameters that are defined.
Based on the results of the calculation, you can create or update kanban rules that become effective on the current date or a future date.

Generate 
Generate calculation lines for all the kanban rules that are associated with the defined policy, and that are valid on the date that the calculation is effective. These rules are included in the calculation. 
Calculate 
Calculate the kanban quantities for the selected kanban rules. You can perform the calculation multiple times. 
Update 
Update the selected kanban rules by using the results of the calculation. A rule is updated if it is valid on the date and time that are defined in the Rule effective date field. If no existing rule is valid on this date and time, a new rule is created. This new rule replaces the original rule on the date and time that are defined in the Rule effective date field.

Fulfilled demand period start date 
Select the date and time from which any past demand transactions that are fulfilled are included in the calculation. 
Fulfilled demand period end date 
Select the date and time until which any past demand transactions that are fulfilled are included in the calculation. 
Demand period start date 
Select the date and time from which any current demand transactions are included in the calculation. 
Demand period end date

Kanban rule 
Select the rule that is included in the calculation. 
Item number 
The identifier of the product that is replenished by the rule. 
Unit 
The unit of measure that is used for the item. 
Fulfilled demand 
The average daily past demand that is calculated for the period that is defined by the Fulfilled demand period start date and Fulfilled demand period end date fields. 
Demand 
The average daily current demand that is calculated for the period that is defined by the Demand period start date and Demand period end date fields. 
Safety stock 
The quantity that is calculated as safety stock for the period that is defined by the Demand period start date and Demand period end date fields. Safety stock is calculated only if this parameter is defined in the kanban quantity calculation policy that is referenced. 
Product quantity 
The product quantity that is defined on the current kanban rule. 
Kanban quantity 
The defined or calculated kanban quantity. When the calculation has the status Created, this field displays the kanban quantity that is defined for the current rule. When the calculation has the status Calculated, this field displays the kanban quantity that is calculated and rounded up. 
Unrounded
