- Navigate to Setup-> Order Management-> Order Allocation Strategy-> New
- Give a name for allocation strategy.
- If user wants future inventory for allocation, check the Future Inventory box given below. For example, inventory that is on order, in transit and not yet received. On hand inventory is always considered for allocation. If user is considering future inventory, the order types can be selected from the box shown below.

- The Allocation Period section helps to limit inventory allocation by defining a specific period before or after the Supply required by date. If allocation period is not defined, this allocation strategy considers all the inventory that is available to allocate. User can limit allocation by specific period before or after supply required by date.

- User can select the allocation method as shown below. Allocate as soon as available before supply required by date/ allocate as close as possible to supply required by date.

- While selecting Available Quantity, NetSuite will allocate a partial quantity of items as soon as any portion of the total amount needed becomes available. NetSuite will allocate the remainder at a future time after another allocation calculation. While selecting Complete Quantity, item allocation takes place only when the total amount needed for the line is available for commitment.

- While selecting Reserved Allocation, NetSuite commits inventory, but can also reallocate it to other orders. While selecting Firm Allocation, NetSuite commits inventory and cannot reallocate it to other orders by the system. User can only reallocate this inventory manually.
