Multi-Level Calculation Setup

Items must be configured with appropriate BOM structures and replenishment settings to use Multi-Level Calculation. This topic describes the setup requirements for both manufacturing and assembly items.

Manufacturing Items Setup

Manufacturing items with nested production BOMs are the primary use case for Multi-Level Calculation. For more information, see Multi-Level Manufacturing Calculations.

To set up a manufacturing item for multi-level calculation

Choose the icon, enter Items, and choose the related link.
Open the Item Card for the manufacturing item.
On the Replenishment FastTab:
- Set Replenishment System to Prod. Order.
- Ensure a certified production BOM is assigned in the Production BOM No. field.
- Ensure a routing is assigned if capacity costs are needed.
For calculations based on production orders, on the Planning FastTab, set Reordering Policy to Order. This makes sure that multi-level production orders are created. For more information, see Calculation (Expected).
Verify that the production BOM includes components that themselves have production BOMs for multiple levels of calculation.

To set up a calculation schedule

Choose the icon, enter Calculation Schedules, and choose the related link.
Create or select a calculation schedule.
Configure the schedule with appropriate calculation methods for manufacturing items.

To automatically apply a calculation schedule when creating calculations

Open the Item Card for the item
On the Prices & Sales FastTab, fill in the Standard Calc. Schedule No. field with the desired calculation schedule

When you create a calculation for this item, the standard calculation schedule is applied automatically.

Assembly Items with Manufacturing Components

Assembly items (Replenishment System = Assembly) can use Multi-Level Calculation when their assembly BOM contains manufacturing components. When an assembly item includes components with Replenishment System = Prod. Order, Multi-Level Calculation automatically processes those manufacturing items and their subordinate BOMs.
