Click Retrieve Demand to retrieve planned demands for this kanban circuit for use in kanban calculations. You can specify the demand source, either Sales Quotation/Customer Order, Customer Schedule/Customer Order, MS/MRP or Production Schedule, and the date range to sample. If the part is planned in master schedule level 1, the system retrieves all master schedule receipt quantities for the date range. If the part is planned on MRP, the system retrieves all net requirements for the date range from the last MRP run. If the part is production scheduled, the system retrieves all component requirements for the part for this date range in current production schedules. If the demand is directly obtained from the sales quotations and the customer orders, the system retrieves all the release planned sales quotations and customer orders that have not been pegged to the supplies already. If the demand is directly obtained from the customer schedules and customer orders, the system retrieves all the planned customer schedules and customer orders that have not been pegged to the supplies already. As an alternative, you can enter your own demand quantity and choose Kanban Circuit as the demand source.
You can also retrieve demand when calculating kanbans using the
Calculate Kanbans assistant.
This activity requires that a demand exists, in either the kanban circuit, the production schedule, the master schedule level 1, the material requirements plan, the sales quotation, the customer order, or the customer cchedule demand source. You can specify the preferred number of days to sample in the Date Range (Days) field on the Kanban Site Setup page.
As a result of this activity the system retrieves a profile of all the demands for this date range and stores them for use in kanban simulations. The new profile overwrites any previous demand profiles. Also, the system calculates the average demand and stores it for use in kanban calculations.
The system generates demand for each working day regardless of the kanban quantity. If there is no demand for a working day, a value of 0 (zero) appears in the Qty Demand field on the Kanban Demands page.
