Understanding Oracle Bill Of Materials (BOM)

Understanding Oracle Bill Of Materials (BOM)

BOM Overview:

A bill of material is a list or Items associated with a parent Item, such as an assembly, and information about how each item relates to the parent item.

• A single level BOM consists of one parent Item and its immediate component Items
• Multilevel BOMs are displayed by linking together single level BOMs stored in the system
• A subassembly is both a parent and a component
• All items in a BOM model, including the parent Item being configured, must be defined in the Item Master and enabled in the Inventory Organization where BOM Model is created
• A BOM Model can be shared among other Inventory Organizations by creating common bills
• After a valid combination of options is selected from BOM Model, a Standard BOM is created to guide manufacturing planning and execution
• Repetitive combinations of option selections can be stored and retrieved as pre-configured Items

BOM Types:

1. Standard Bill
2. Model Bill
3. Option Class
4. Planning Bill

BOM Models:

Create Model bills to represent products and service that allow user-selected options:

- Option Classes are groups of optional items
- Optional Items
- Required Items

Model bills and Option Class bills of material can include:

- Stock Items
- Assemble-to-Order Models
- Mandatory and Optional Components

PTO and ATO BOM Models:

•ATO BOM Models:

- Represent product models that require assembly “downstream” in Oracle Work In Process
- Are assembled using manufacturing work orders that can be costed

•PTO BOM Models:

- Represent product Models in which included items appear on pick slips and selected when the order ships
- Are not costed

Configurable PTO and ATO BOM Models:

- The inventory Item that represents the top level in your BOM Model must have the BOM Item Type attribute set to Model
- PTO and ATO BOM Models can contain Standard Items and Option Classes as components
- ATO and PTO BOM Models can also contain other ATO BOM Models as components
- An ATO BOM Model cannot contain a PTO BOM Model
- A PTO BOM Model can contain a PTO BOM Model

Implicit Rules:

Basic rules are included with Oracle Bills of Material:
- Optional or Required
- Mutually Exclusive
- Maximum and Minimum Quantity
- Quantity Cascade

• These rules provided by Oracle Bills of Material are called Implicit Rules.
• Oracle Configurator honors these rules as well as the rules defined using Oracle Configurator Developer

Option Classes:

Option Class is an element of a Configuration Model.The purpose of Option Classes are to group and prevent viable alternatives. The end user typically selects one or more options from each Option Class during runtime to create a valid configuration.

Option Class Selection Rules:

BOM Model rules for selecting options from an Option Class during order entry:

• Required and Mutually exclusive:You must select one and only one Item in this Option Class
• Required:You must select one or more optional items in this Option Class
• Optional and Mutually Exclusive:You can select only one optional item in this Option Class
• Optional:Select none, some, or all optional items in this Option Class
