Multi-Level BOM Explosion
The setting BOM explosion: multi-level means that multiple levels of the BOM of a configurable material are exploded in the sales order, if the configuration profiles of the configurable assemblies also support BOM explosion. You can configure assemblies across multiple levels.
Variant product MULTIMEDIA_WORKSTATION supports multi-level BOM explosion. The BOM contains configurable material PC. This material supports single-level BOM explosion. The BOM of the PC contains another configurable material MONITOR.
All configurable items are configured in the sales order, not only sales-relevant items.
You can use filters in the configuration profile to restrict the scope of the BOM items (see
Filters for BOM Explosion).
- Sales-relevant items are copied to the sales order as order items.
- The characteristic values assigned to each configured item are saved.
- In MRP, components and operations selected depend on the characteristic values assigned according to the principles of low-level configuration (see
- If you define selection conditions for the BOM items of a subordinate configurable assembly, and these selection conditions refer to the characteristics of the assembly, you must use the object variable $PARENT to refer to the characteristics.
The selection conditions for BOM components of the PC must refer to the characteristics of the monitor with object variable $PARENT – for example,
$PARENT.MANUFACTURER = 'Sony'.
This type of order processing lets you use constraints to infer values for configurable materials on different levels.
The configuration profile of the header material has the configuration parameter BOM explosion: multi-level.
The subordinate materials whose BOMs are to be exploded in the sales order must also have a BOM explosion parameter (single-level or, preferably, multi-level).
Create a sales order and enter the configurable material as an order item.
You see the configuration editor, where you assign values to the characteristics of the header material. You can then display the result of the BOM explosion by choosing Result.If any of the selected BOM components are also configurable materials, you can assign values to the characteristics of these materials. Depending on the configuration parameters, the BOMs of these materials are exploded on the result screen.
The header material appears as a sales order item. If the BOM contains further sales-relevant items, these are included as sub-items. The characteristic values assigned to the header material and the subordinate configurable materials are saved.
In the planned order or production order, BOM components and operations for the configured materials are determined according to the characteristic values assigned.
