Parent/Component Relationships
The system uses BOMs, each a collection of parent/component relationships, for the planning and control of manufacturing. This slide illustrates the bill of material for the medical ultrasound (device 01010). The BOM shows three levels in the product structure below the end item 01010, the medical ultrasound.
• Not all level 1 components are shown; several more are needed to build the end item.
• The probe unit has two components: a standard connector and a transducer.
• The standard connector also has two components.
Alternate Product Structure or Formula
Different formulas for different batch sizes of product or alternate product structures used in different circumstances require multiple BOMs for the same item. This is done by adding a BOM code in Product Structure Code Maintenance or Formula Code Maintenance and then using this BOM code as the parent in Product Structure Maintenance or Formula Maintenance. A BOM code uniquely identifying a product structure or formula.
The normal situation is to have the BOM code be the same as the item number. When several alternate structures are available, they are given other identifiers. The alternate BOM you use most often can be linked to the item number in Item Planning Data Maintenance.
