The running user of the dashboard is the user on whose perspective the data is displayed on the dashboard. For example, if the Running User is the manager, any user who can see the dashboard can see what the manager can see on it irrespective of the sharing rules.
Alternatively, we can create a dynamic dashboard that changes the data according to the user who opens it.
To create dynamic dashboards, perform the following steps:
From the Dashboards tab, create a new dashboard or edit an existing one.
Click on the down arrow next to the View dashboard as field, as shown in the following screenshot:
Select Run as logged-in user and click on OK.
Save the dashboard.
