Process: Order BOM

Purpose

You use this processing option if you want to make customer-specific changes to the BOM of a material that you configure in the sales order. In the sales order, you assign values to the characteristics of the header material, but the BOM is not exploded in the sales order.

The BOM components that match these values are not determined until you call a special processing function. Subordinate configurable materials can be configured in this function, and you can make order-specific changes to the BOM.

There are 2 types of order BOMs:

• The result-oriented order BOM saves the configured BOM with the manual changes.
• The knowledge-based order BOM saves the super BOM with all manual changes and dependencies, not the configured BOM. When you explode the BOM, the dependencies are processed dynamically and only the selected items are displayed.

If you change the characteristic values assigned to the material in transaction VA01, VA02, or CU51, this may affect the order BOM.

Prerequisites

The configuration profile of the configurable material has the Process: Order BOM indicator selected, with a single-level or multi-level BOM explosion.

Process Flow

Maintenance of Order BOM not Allowed in Sales Order

1. Create a sales order and enter the configurable material as an order item.
2. You see the configuration editor, where you assign values to the characteristics of the header material. As you enter characteristic values, dependencies for the characteristics and values are processed.

The BOM is not exploded in the sales order. You cannot assign values to subordinate configurable materials in the sales order.

The header material appears as a sales order item.

3. Once you have saved the sales order, you can process the BOM for the sales order by choosing Bill of material ® Order BOM ® Maintain multi-level from the bills of material menu. The values assigned to the material in the sales order are displayed and cannot be changed.

Maintenance of Order BOM Allowed in Sales Order

You can only use this function if you select Result-oriented BOM in the configuration profile first.

1. Create a sales order and enter the configurable material as an order item.
2. You see the configuration editor, where you assign values to the characteristics of the material. As you enter characteristic values, dependencies for the characteristics and values are processed.
3. Choose Engineering to process the order BOM.

• You can assign values to subordinate configurable materials or change values already assigned.
• Exit configuration and return to the sales order.

The order BOM is saved as a result-oriented order BOM when you save the sales order.

4. The header material is shown in the sales order as an order item.

Result

In material requirements planning (MRP), requirements are determined for the order item. To ensure that MRP checks whether a material has an order BOM, set the Sales order BOM indicator in Customizing by choosing Planning ® BOM Explosion/Determine Routing ® Define BOM explosion control.
