Data Categories in Salesforce Knowledge

Last Updated: Feb 16, 2026

Finding accurate support information quickly can be challenging without a structured knowledge system. Salesforce Knowledge is a centralized knowledge base that stores and organizes articles, documentation, and support content. It helps teams deliver consistent answers and enables users to quickly find reliable information.

Data Categories organize this content by topic, product, region, or any logical hierarchy. They serve two main purposes: helping users navigate and filter articles efficiently, and controlling who can access specific knowledge content based on roles or permissions. As a result, they are essential for maintaining clarity and structure within the knowledge base.

Quick Answer
Data Categories group Salesforce Knowledge articles into logical structures that make content easier to find and manage. They also control article visibility for different users and channels. The key benefits include:

• Enhanced filtering and navigation in the knowledge base
• Visibility managed through category assignments and role or channel permissions
• Users only see articles available to them in Knowledge and portal experiences

What are Data Categories in Salesforce Knowledge?

Data Categories in Salesforce Knowledge are a hierarchical classification system used to organize knowledge articles within a Salesforce org. A Data Category Group is the top-level container that represents a broad dimension of classification (for example, Products, Regions, or Services). Inside each group, you define Data Categories arranged in parent–child levels that form the hierarchy used to tag and organize articles. You can create multiple groups, and each group can include several levels of nested categories to reflect how your information is structured.

For example: Products → Hardware → Laptops → Model X

Where they’re used:

• Classifying Knowledge articles by topic, product, or audience
• Powering search and filter experiences in Knowledge and portals
• Supporting visibility rules that control who can access specific content

What if you don’t assign categories?
If an article isn’t assigned to any Data Category, it won’t benefit from category-based filtering or navigation. Depending on your visibility configuration, the article may still be accessible through direct search or links, but users won’t be able to discover it via category filters, and category-based access rules won’t apply to it.

AC Knowledge Management for Salesforce: How to Use It to Increase Support Efficiency

Salesforce is an incredibly powerful CRM platform that enables organizations to manage their customer relations, and more. But keeping track of everything can be a challenge, especially if you’re relying on manual processes or outdated tools. That’s why we created AC Knowledge Management Enterprise — a 100% native to Salesforce app that makes knowledge management on Experience Cloud smooth and holistic.

How to Create a Data Categories in Salesforce

Use Data Category Groups to define broad classification dimensions, then add hierarchical categories within each group.

To create a Data Category Group:

1. Go to Setup.
2. In the Quick Find box, search for Data Category Setup and open it.
3. Click New to create a Data Category Group.
4. Enter a Name for the group (for example, Products).
5. (Optional) Add a Description.
6. Click Save.
7. Select the newly created group to start adding categories.

To Add Categories and Build the Hierarchy:

1. With the group open, enter a Category Name in the input field.
2. Click Add to create a parent category.
   
3. To create a child category, open the parent’s Actions menu.
4. Choose Add Child Category.
   
5. Enter the child category name and click Add.
6. Repeat as needed to build additional levels in the hierarchy.
7. Click Save to apply changes.

Note: UI wording and navigation may vary by Salesforce edition and enabled features.

How to Assign Data Categories to Knowledge Articles

Creating categories is only the first step. Articles must be assigned to the appropriate categories so they can be filtered, discovered, and governed by visibility rules. Otherwise, they won’t function as intended. Below are simple steps to guide you through the process:

1. Open the Knowledge article you want to classify.
2. Click Edit (or open the draft version if versioning is enabled).
3. Locate the Data Categories section or field on the article layout.
4. Choose one or more categories from the relevant Data Category Group(s).
5. Save your changes.
6. Publish or Validate the article according to your workflow.

Note: The exact placement of the Data Categories field and publish/validate actions can differ by layout and configuration.

Quick Tip:
After assigning categories, verify how the article appears for different roles or channels. This helps confirm that category-based visibility behaves as expected before broad release.

Default Data Categories Visibility Settings

Data Category Visibility controls which knowledge articles users can see based on assigned data categories. By setting default visibility for a category group, you define the scope of content available to a user or profile. There are three variations of visibility:

• All Categories: Users can view articles from every category within the category group.
• None: Users cannot view articles from the category group.
• Custom: You specify exactly which categories users can access. In practice, this means users will only see articles assigned to the selected categories. If no categories are assigned, users will only see uncategorized articles.

Data Category Visibility on the profile level

It is also possible to configure Data Category visibility using profiles or permission sets in Salesforce. This allows you to define which articles users can access based on their role, audience, or channel (for example, internal support agents vs. portal users, partners vs. customers, or Tier 1 vs. Tier 2 support teams).

This approach is typically used when different groups of users should see different knowledge content — such as region-specific documentation (EMEA vs. North America), product-line access (Hardware vs. Software), partner-only materials, or role-based procedures (agents vs. managers). If users report that they see the wrong articles or cannot find expected content, check their profile or permission set Data Category Visibility settings first.

You can specify for each profile which categories are visible and which articles will not be available to users with that profile:

• Go to Setup → Profiles → select the appropriate profile
• Data Category Visibility → configure visibility for the required categories.

If you’re configuring Knowledge for Experience Cloud users and want to get visibility and navigation right the first time, our team can help you design and implement the optimal setup in Salesforce.

Support for Data Categories Salesforce Experience Cloud

Out of the box, Data Categories aren’t available on Experience Cloud sites. This means there is no filtering or navigation functionality available on the site, so portal users can’t browse Knowledge content using the same category structure that organizes articles internally, which can make discovery and navigation less intuitive.

A common workaround is mapping Data Categories to Chatter Topics and using Topics for navigation and filtering. However, this approach is a compromise: Topics don’t fully reflect the original category hierarchy, require additional maintenance, and may not align with visibility logic or user expectations.

To address this gap, Advanced Communities developed AC Knowledge Management Enterprise, a Lightning-native component designed specifically for Knowledge in Experience Cloud. It provides:

• Filtering and navigation based on Data Categories and article types
• Advanced, multi-level Knowledge navigation tailored for portal users
• The ability to create and manage Knowledge articles directly from the community
• A structured, scalable Knowledge experience aligned with internal classification
• Improved discoverability and user experience without custom workarounds
