*** Update 11/20/2017 The Portfolio Dashboard app is no longer available in the store. Please take a look at the new Power BI Content pack as a replacement for the same kind of views of your Project data https://blogs.technet.microsoft.com/projectsupport/2017/10/26/a-new-project-online-content-pack-for-power-bi/ ***
This week saw the release of the portfolio apps that will present dashboards of your Project Online data. The iPad version is available from the Apple store and the web version is in the Office store. The announcement blog post can be found at https://blogs.office.com/2016/04/19/new-office-365-project-portfolio-dashboard-apps-are-live.
One quick note on permissions – even if you are in Project Permission mode you will need to use the following SharePoint groups to give users the right level of access to the data the dashboards are using.
Administrator for Project Web App
Portfolio Manager for Project Web App
Portfolio Viewer for Project Web App
Site Settings, Site Permissions will take you to the right page to access these groups and add users.
Also please note that the dashboards do not use the project security model of groups and categories so users given such access will see all of the projects – same as for the OData feeds.
If a user isn’t in one of these groups (and they are not a Site Collection Administrator or Global Admin) then the error they will see is:
Failed to load dashboard definition for 'null'. Error: List 'MicrosoftPortfolioCache' does not exist at site with URL 'https://yourpwa-5e1162060649a6.sharepoint.com/sites/pwa/Dashboard'.
Enjoy the new apps!
