## Summary of Entity class rules

Entity class rules enable automatic classification of entities at the table level in ServiceNow.
When a new entity is created for a table, the associated entity class is automatically assigned based on these rules.
This classification helps organize and tag entities consistently, improving data management and categorization.

## Key Features

* **Automatic Class Assignment:** Entities inherit their class from the table-level entity class rule when created.
* **Entity Class Rule Filters:** Filters can be added to assign different subclasses to records within the same table, allowing more granular classification beyond a single class per table.
* **Filter Priority and Conditions:** Filters have priorities and conditions that determine which subclass is assigned to an entity, ensuring the most relevant classification based on record attributes.
* **Workspace Integration:** Entity class rules are accessible under the Lists section in the workspace, where details and filters can be reviewed and managed.

## Logic for Assigning Entity Classes

Entity class assignment follows a priority and condition-based logic:

* If an entity's source record matches a subclass rule filter condition, that subclass is assigned.
* If multiple filter conditions are satisfied, the subclass with the highest priority is assigned.
* If no filters are matched, the parent entity class associated with the table is assigned by default.

## Practical Usage for ServiceNow Customers

* Create an **entity class rule** for a table to define the default class for entities created on that table.
* Configure **entity class rule filters** to apply more detailed subclassifications based on specific record attributes, enabling more precise entity tagging and categorization.
* Use filter priorities and conditions to control how entities are classified automatically, which helps maintain consistent and meaningful entity data in your CMDB or other tables.  
Entity class rules help to assign classes to the entities at the table level. Any new entity created on the table gets that entity class automatically. Entity classes are used to tag your entities.

When you create an entity for a table, the class associated with that table automatically gets assigned to the entity. You can set a new rule for the entity class. Entity class rules provide the categories of the entities at the
class level. The Entity class rules option is displayed under Lists in the workspace view. Click an Entity class rule to display its details.  
The Details tab in the Entity class rules form displays the following information:{#entity-class-rules-in-risk-ws__table_b22_ynv_lqb__entry__2}

| Field | Description |
|-|-|
| Table | Name of the table that the entity class is associated with after creating an entity class rule. |
| Class | Name of the entity class to be associated with the table that uses the new entity class rule. |
[Table 1. Details tab in the Entity class rules page]

{#entity-class-rules-in-risk-ws__table_b22_ynv_lqb}

## Entity class rule filter {#entity-class-rules-in-risk-ws__section_tjq_f31_g5b}

Entity class rule filter is added in the entity class rule page to provide additional filters. Earlier, records of a table can be associated to only one entity class.
Using the entity class rule filter,
you can associate different classes to the records of the same table.  
The Entity class rule filter table displays the following information:{#entity-class-rules-in-risk-ws__table_yfz_jhh_g5b__entry__2}

| Field | Description |
|-|-|
| Filter Priority | Filter priority is the range for the subclass. The class is populated in the entity form based on the priority given. |
| Subclass | Subclass is the child class of the parent class that is displayed in the details tab of entity class rules. |
| Filter Condition | Filter Condition is used to filter out the records of the table that defines the entity class rule. For example, if there are two subclasses with different condition then the parent class is populated instead of the subclasses. Note: The subclasses are displayed in the entity forms only if they meet the same filter condition. |

## Logic for assigning entity classes {#entity-class-rules-in-risk-ws__section_zkc_mbs_h5b}

Assume that there is a record in the cmdb_ci_linux_server table and an entity class rule associated to this table. The entity class rule has these class rule filters:
Figure 1. Entity class rule

Scenario 1: If the entity's source record belongs to the cmdb_ci_linux_server table and matches all the conditions of the second filter, then the entity's class is auto-populated as sub class,
Department.

Scenario 2: If the entity's source record belongs to the cmdb_ci_linux_server table and its name starts with lnux (satisfies both the filters), then the sub class Application is
auto-populated as an entity class.

Scenario 3: If the entity's source record doesn't satisfy any of the class rule filters, then the class Linux Server is auto-populated as an entity class.
* **[Create an entity class rule](https://servicenow-prod.fluidtopics.net/1GpIcsLzbvetk7O0iPO9uA)**   
  Create a rule for an entity class. Entity class rules provide the classification of the entities at the class level. You can create a new entity class rule for an entity class that is associated with a table. After creating the new entity class rule, the Entity class rules table is updated with the new record.
* **[Create an entity class rule filter](https://servicenow-prod.fluidtopics.net/T~7hH5C68qXD4kmi754h2A)**   
  You can create an entity class rule filter to assign classes at the filter level on the same table that is defined on the class rule.
