The Inventory Template Overview tab
Summarize
Summary of The Inventory Template Overview tab
The Inventory Template Overview tab is a design-time verification interface within inventory template records in ServiceNow. It displays the complete template hierarchy as an expandable tree, showing resolved names of related templates to help you visualize and validate the template structure before instantiation. This tab does not create any configuration items (CIs) during interaction.

The Overview tab is the default view upon opening an inventory template record and is one of three tabs, alongside Details and Related Templates. It is available in both the SOW workspace and the Network Inventory workspace.
Key Features
- Tree-based hierarchy view: The left pane presents the full inventory template composition graph, with the root template at the top and all related templates as expandable child nodes. It supports multiple levels of nesting to reflect complex inventory structures accurately.
- Detail pane: The right pane shows read-only attributes of the selected template node, including Name, Parent, Inventory model, Relationship type, Default field values, and Name Pattern if defined. Any edits to these fields are made through the 'View details' option outside this tab.
- Performance optimization: To maintain responsiveness, the tree initially loads only the first eight children per expanded node, with a 'Show More' link to load additional children on demand.
- Validation integration: The Overview tab runs validation checks on resolved template names using registered validation providers. Validation errors are flagged with a red Error badge on the tree node and a detailed error banner in the detail pane.
Practical Use for ServiceNow Customers
This tab allows customers to quickly assess and validate the structure and naming of inventory templates before deployment, reducing errors and ensuring naming conventions are correctly applied. It helps visualize complex inventory hierarchies and pinpoint issues early through integrated validation results, improving inventory management accuracy and efficiency.
The Inventory Template Overview tab is a design-time verification surface on inventory template records. It shows the full template hierarchy as a tree with each related template's resolved name as the node label, and runs validation against the resolved hierarchy. No configuration items (CIs) are created from the actions you take in this view.
Where the Overview tab fits
The Overview tab opens by default when you open an inventory template record. It is the first of three tabs:
-
Overview — the tree-based hierarchy view described in this topic.
-
Details — the inventory template's own header fields (Name, Inventory model, Default field values, Version).
-
Related Templates — the flat list of child related templates, with editable fields including Name Pattern.
The Overview tab is available in both the SOW workspace and the Network Inventory workspace.
The two parts of the Overview
The Overview tab is split into two regions:
-
The tree on the left renders the inventory template at the root, with all related templates beneath it as expandable child nodes. Each node's label is the resolved name that the related template will produce when the template is instantiated.
-
The detail pane on the right shows the attributes of whichever tree node is currently selected — Name, Parent, Inventory model, Relationship type, Default field values, and Name Pattern where one is defined.
The detail pane is read-only. To edit any of the fields shown, use the View details button described in the task topic for defining a naming pattern.
How the tree represents the hierarchy
The tree traverses the inventory template's full composition graph. Each related template that itself has related templates is rendered as an expandable node — selecting the chevron beside the node reveals its children, which may in turn be expandable.
The hierarchy can extend several levels deep. For example, the ASR9006 Edge Template expands to slots at the first level, which expand to card templates at the second level, which expand to sub-slots, which expand further to interface card templates, which expand to ports — five levels of nesting under the equipment root.
For performance, the tree loads only the first eight children of each expanded node. When a parent has more than eight children, the tree displays a Show More link beneath the visible children to load additional nodes.
Where validation results appear
When the Overview evaluates the hierarchy, registered validation providers run against the resolved names. Any related template that fails validation displays a red Error badge on the right side of its tree node. Selecting an affected node also shows a red Validation failed banner beneath the detail pane that describes the specific error.
