Workspaces are the place for collaboration and the collection of work for you and others in your department. Within the workspace, you and your colleagues can set up permissions, security, and data refresh of the reports.
For more information about workspaces, please read the UMS Power BI Workspaces & Apps page and Microsoft's Roles in workspaces in Power BI page.
If you or your department doesn't have a workspace, you can request one through this Power BI Workspace Creation Request form.
UMS recommends using SharePoint for saving Power BI (pbix) files or data source files. It is secure and works best with Power BI. For more information about SharePoint, please read our Sync SharePoint User Libraries to Your Computer page.
