Categorizing entity records in Microsoft Dynamics 365 helps you tag the records so that you can easily search them. Use the Category entity to create and manage a hierarchical structure of categories in Dynamics 365, and then associate entity records to one or more categories.

This feature was introduced in CRM Online 2016 Update 1 and CRM 2016 Service Pack 1 (on-premises).

A category can have multiple child categories, but a child category can have only one parent category. Deleting a parent Category record automatically deletes all its child records and entity associations. You define a parent category for a category using the Category.ParentCategoryId attribute.

Use the Category.SequenceNumber attribute to programmatically define the display order for categories in the hierarchy. When you a add a new category using the web client, it is automatically added after the last category in the hierarchy. You can also use the Category.CategoryNumber attribute to programmatically set or update a number for category to help you easily distinguish a group of categories. Category number can be set to any value programmatically, but is automatically set when you create a category using the web client based on the auto-numbering prefix specified by the administrator for categories in the web client (Settings > Administration > Auto-Numbering > Categories tab).

You can associate Category records with system and custom entity records by using relationships and connections. A category record can be associated with different entity records. For example, you can programmatically associate a Category record with an Account, Contact and Incident records.

By default, there is a many-to-many relationship available between the Category and KnowledgeArticle entity, and the entity record associations are stored in the KnowledgeArticlesCategories entity.
