Mass Update and CSV Import With Demand Planning
You can also use the Mass Update function to update item records for demand planning. Go to Lists > Mass Update > Mass Updates and click General. Under Items, click the type of item to update.
For example, on the Mass Update Fields subtab, you can update the selection in the Replenishment Method field on item records.
For more information about mass updates, see Mass Changes or Updates.
When updating inventory or assembly items using Mass Update, you cannot perform a mass update unless certain auto-calculate settings are disabled.
Account administrators and other users with Import CSV File permission can use the Import Assistant to import demand plans. For more information, see Importing Demand Planning Data for Items. For general information about using CSV import for items, see Items Import.
