is it possible to create dashboard filtered by the current logged in user only ? For example when a user logs in, he should see records created only by him and not everyone else's... Please let me know
depending on the edition you are using, if you have dynamic dashboards enabled, you can configure the running user for the dashboard as either a specific user or the current logged-in user.
refer the below links on how to setup dynamic dashboard and configure the running user for the dashboard.
