Multi-component models and assets in Enterprise Asset Management
Summarize
Summary of Multi-component models and assets in Enterprise Asset Management
Multi-component models and assets in ServiceNow Enterprise Asset Management (EAM) enable detailed tracking and maintenance of complex enterprise assets composed of multiple components. A multi-component model links one or more model components, which may be consumable or serialized assets, allowing you to manage components individually or as part of an assembled asset.

Key Features
- Multi-component Model Properties: Each component has three exclusive properties:
- Required: Essential components that cannot be permanently removed.
- Hot swappable: Components that can be replaced while the parent asset is operational.
- Repairable: Components that can be repaired upon failure.
- Types of Multi-component Models: Pre-assembled and user-assembled models, which can be converted to simple models by removing all components while in the Build state.
- Multi-component Assets: Created from multi-component models and can be serialized or consumable. Serialized components create individual child assets; identical consumable components are merged into a single child asset with combined quantity.
- Pre-assembled vs User-assembled Assets:
- Pre-assembled child assets are automatically created with the parent asset in the same stockroom and inherit key properties.
- User-assembled assets require manual or automatic assembly from stockroom components, with error handling if components are unavailable.
- Add-on assets can be added to pre-assembled assets and update the parent asset type accordingly.
- Child Asset Swapping: Child assets can be swapped with others of the same model component when the parent asset is in certain states (e.g., In Use, In Maintenance, In Stock, Defective).
- Multiple Components Addition: You can add multiple quantities of components simultaneously. Serialized components create multiple records for each quantity, while consumable components create a single record with the total quantity.
- Component Number Usage:
- Consumable components use component numbers to identify and track child assets, which are prefixed in the child asset display name.
- Serialized components may optionally use component numbers if quantity is one; otherwise, component numbers are autogenerated. Component numbers serve as asset tags if no asset tag is assigned, but an asset tag overrides the component number.
Practical Benefits for ServiceNow Customers
By leveraging multi-component models and assets, customers can manage complex enterprise assets with granular control over each component’s lifecycle, including maintenance, repair, replacement, and tracking. The ability to distinguish between pre-assembled and user-assembled assets ensures flexibility in how assets are constructed and maintained. Component properties like hot-swappability and repairability streamline operational workflows and reduce downtime. Managing quantities and component numbers enhances inventory accuracy and asset traceability, especially for consumables without serial numbers.
Multi-component models and multi-components assets help you track the maintenance of your enterprise assets.
Multi-component model
An enterprise model that is associated with one or more model components is defined as a multi-component model. Each model component can be a consumable or enterprise model. The same model can be listed more than once as a model component.
| Property | Description |
|---|---|
| Required | If this property is set to true, the model component is essential for the multi-component model to function and cannot be removed permanently. |
| Hot swappable | If this property is set to true, the model component can be replaced while the multi-component model is operational. |
| Repairable | If this property is set to true, the model component can be repaired when it fails. |
The Enterprise Asset Management application supports two types of multi-component models: pre-assembled and user-assembled. You can convert a pre-assembled or user-assembled model to a simple model by removing all of its associated model components while it is in the Build state.
Multi-component asset
Multi-component assets are created from a multi-component model.
The Enterprise Asset Management application supports two types of multi-component assets: serialized assets and consumable assets. Serialized child assets are created for model components. Consumable model components that are listed more than once are merged into a single consumable child asset with the combined component quantity.
Pre-assembled and user-assembled assets
-
Pre-assembled asset: Child assets are automatically created when a parent asset is created. These child assets are created and placed in the same stockroom that the parent asset was created in. Each child asset inherits various properties from the parent asset, including the asset stockroom, state, and sub status.
If you want to add additional child assets to an existing parent asset, you can use add-on assets. These assets do not have to be defined through the original model components. If you use an add-on asset, the Asset type of the parent asset is automatically updated to Pre-assembled with add-on.
- User-assembled asset: Assets that are assembled using components from the parent asset stockroom. You can assemble these assets using either of the following methods:
- Manual assembly: Manually select the required components and assemble the asset by using the Assemble button in the asset record. For details, see Select assets for user-assembled asset.
- Automatic assembly: Automatically select the required components and assemble the asset by using the Auto-assemble button in the asset record. If the required quantity of components is unavailable in your stockrooms, an error appears. You must then assemble the asset manually.
- In Use
- In Maintenance
- In Stock Defective
- In Stock Pending Repair
Multiple components for an enterprise model
- For serialized components, each row in the dialog box splits into multiple model components based on the quantity that you specify in the Quantity field. For example, if you set the Quantity field to 10 for a given row, 10 model component records are created for that row.
- For consumable components, one model component record is created per row. Each record indicates the quantity that you specify in the Quantity field. For example, if you set the Quantity field to 10 for a given row, only one model component record is created with a quantity of 10.
Component number usage for consumable components
Since consumable assets don't have asset tags or serial numbers, the Component number field in your model component records can help you identify and track your consumable child assets. This component number is propagated to the display name of the child asset as a prefix.
Component number usage for serialized components
Since serialized assets can have asset tags, component numbers are optional for serialized child assets. You can specify a component number only if you set the Quantity field of the Add model components dialog box to 1. If you set this field to a value greater than one, the component number is generated automatically. If a serialized child asset does not have an asset tag, the component number is propagated as the asset tag. Any asset tag that you later add overrides the component number.
