Dashboard org licensing limits
Key Takeaway
The limit on dynamic dashboards applies per org and depends on the edition. It counts dashboards, not the people who view them.
A dynamic dashboard shows each viewer only the data they have access to. Each org can have only a set number of dynamic dashboards, and that number depends on the Salesforce edition. As an admin, you need to know these limits, how to spot when the org has hit them, and how to free up or add capacity.
What a dynamic dashboard is
A dynamic dashboard runs as the logged-in user, so each viewer sees data filtered to their own access. A static dashboard instead runs as one specific user, called the running user.
In Lightning Experience, you make a dashboard dynamic by setting "View Dashboard As" to "The dashboard viewer". Users need the "Manage Dynamic Dashboards" permission to create, edit, and delete dynamic dashboards.
