RE: Need to convert Personal Dashboard to System Dashboard in CRM 2016
There are two ways of creating a 'system dashboard'
1. In order to retain the ownership of the dashboard which you created, select the dashboard and select 'Share' (in the actions pane in the ribbon bar) and then assign the read, write, delete, append, assign and share permission to the user(s) / team(s).
2. Another way to is create the dashboard directly in the solution and publish it. This dashboard will be available in system dashboard. Select the dashboard and then 'Set this as default' .(You will see this option right above the definition are. Hint: Set the component type as 'Dashboard')
