Creating Item Supply Plans

After you create demand plans, you can create individual supply plans for specified items. The supply plan details orders to be placed for items based on the beginning inventory level, safety stock level, lead time, and projected demand.

Important:

Time-Phased Planning is no longer supported. It has been replaced by Supply Planning (MRP).

When you generate supply plans from your demand plans, NetSuite creates future work orders or purchase orders that replenish items in appropriate quantities.

For more information about which orders are included in demand plan calculations, see Calculating Item Demand.

To create item supply plans:

Go to Transactions > Demand Planning > Generate Item Supply Plan.
If you use NetSuite OneWorld, select a subsidiary.
If you use the Multi-Location Inventory feature, select a location.

The items list shows only items for the selected location that are time-phased replenishment items.
Select a department, if you track them.
Select a class, if you track them.
If you use the Distribution Resource Planning feature, choose a setting for the Plan Through Distribution Network box.

When this box is checked, NetSuite runs demand planning calculations across all locations and items within the network.
- First, NetSuite evaluates affected items based on the selection
  - All assemblies associated with this item
  - All components associated with this item
- Next, NetSuite evaluates all locations based on the selection
  - All source locations in the Bill of Distribution associated with this location
  - All destination locations in the Bill of Distribution associated with this location
The Start Date field determines the earliest transaction date that can be shown on any new orders created. Verify the default current date or enter another date.
In the End Date field, enter the last date in the range you want to create orders through. Orders are created based on item demand on or prior to the end date selected.

For example, if you enter July 30, supply plans are created based on demand between the current date and July 30th.
Select all items you want to create supply plans for.
Click Submit.

When you click Submit, NetSuite creates supply plans for the selected items.

Note:

If you use the Assemblies feature, any linked items also have their supply plan created. For example, if an assembly has a component item that is set to time-phased replenishment, NetSuite generates the component item supply plan.

In the Item Supply Plan list, you can open individual plans by clicking the plan name.

When you view an individual plan, the Item Supply Plan page displays the orders to be created for the item. The orders are created based on information from the Generate Supply Plan page.

When calculating the supply plan, NetSuite considers prior transactions as existing supply orders on the start date of the planning calculation:

A purchase order that is not closed
A purchase order that is not fully received
A purchase order that has a date that is before the start date

If an existing purchase order does not have an expected receipt date, the receipt date is the purchase order’s transaction date.

Manufacturing Routings

If you generate orders and also use the Manufacturing Routing and Demand Planning features, you can define production scheduling methods on work orders. For more information, see Production Scheduling Methods Overview and Supply Planning and Routing.
