Summary of Enterprise Asset Management normalization

The Enterprise Asset Management (EAM) normalization process in ServiceNow standardizes your enterprise model data, including manufacturer, model name, model number, and model type. It achieves this by comparing discovered data against a repository of normalized equivalents maintained in the Enterprise Asset Management Content Service. Normalization ensures consistency and accuracy in your asset records, which is essential for effective asset management.

You can perform normalization either manually by updating model records with content service data or automatically by using scheduled jobs that synchronize and normalize your asset data.

Scheduled Jobs for Normalization

Several scheduled jobs support ongoing normalization and content synchronization:

EAM - Daily Job: Runs once at the initial normalization start to set data pull timing and checks lifecycle end dates to update lifecycle phases accordingly.
EAM - Content Upload: Runs daily to upload custom content from your custom tables to the Content Service, if you have opted in.
EAM - Enterprise Lifecycles: Updates model records with changes in lifecycle definitions, such as newly created or deleted lifecycles.
EAM - Normalization: Normalizes all models that have not yet been normalized.
EAM - Apply latest content changes: Applies updates from content tables to the Content Service to keep your data current.

Normalization Tables Installed

Activating the Enterprise Asset Management application installs several tables critical for managing normalized data and content synchronization:

Custom Enterprise Model Type, Manufacturer, Product Model, Model Library: Store your custom enterprise model data.
Enterprise Model Type, Manufacturer, Product Model, Model Library: Contain normalized enterprise model records.
Enterprise Lifecycle Definition: Holds lifecycle phase information and associated dates for models.
EAM Content Audit: Tracks changes in content values for auditing purposes.
Manage Enterprise Library: Supports import and export of content data.
Enterprise Asset Configurations: Stores opt-in or opt-out configuration settings related to the Content Service.

Practical Benefits

By leveraging the EAM normalization process and associated scheduled jobs, ServiceNow customers can ensure their asset data is consistent, accurate, and aligned with industry-recognized standards. This improves asset tracking, reporting, and lifecycle management across the enterprise, enabling better decision-making and operational efficiency.

The Enterprise Asset Management normalization process enables you to normalize your manufacturer, model name, model number, and model type data of your enterprise models.

Normalization overview

The normalization process compares the discovered manufacturer, discovered model, discovered model type, and the discovered model number values against the ServiceNow repository of normalized equivalents in the Enterprise Asset Management Content Service.

To standardize your enterprise models, the data must be normalized. You can manually update the model records with the normalization content, or you can compare your data against the Enterprise Asset Management Content Service.

Scheduled jobs for Normalization

The following are the scheduled jobs that run during the normalization process.


Scheduled job	Description
EAM - Daily Job	Sets the time when data is pulled by the Enterprise Asset Management Content Service. This job runs only once, when the normalization process is started for the first time. If a model has gone beyond its end of its lifecycle date, this job enables the Content lifecycle phase check box in the Enterprise Model Lifecycle tab in a model record.
EAM - Content Upload	A daily job that uploads any content to the Enterprise Asset Management Content Service that you have added in the following custom tables: Custom Enterprise Model Type [sn_eam_cd_custom_model_type] Custom Enterprise Manufacturer [sn_eam_cd_custom_manufacturer Custom Enterprise Product Model [sn_eam_cd_custom_product_model] Custom Enterprise Model Library [sn_eam_cd_custom_model_library] Note: This job only runs if you have opted in to the Enterprise Asset Management Content Service.
EAM - Enterprise Lifecycles	Updates the model record with information about newly created or deleted life cycles.
EAM - Normalization	Normalizes all the models that haven't been normalized.
EAM - Apply latest content changes	Updates any changes in the content tables to the Enterprise Asset Management Content Service.
