The following changes apply to the Power BI content packs that were available for install from powerbi.com and have no impact on any existing Power BI reports that you have installed or published on your own.
Starting September 1, 2019, content packs are no longer supported on Power BI online. At this point, updates to existing content packs are no longer supported. For more information, see the annoucement on the Power BI blog: https://powerbi.microsoft.com/en-us/blog/announcing-power-bi-template-apps-general-availability
Specifically for Dynamics 365 Business Central and Dynamics NAV, our published content packs have a number of known issues. So because updates are no longer supported, these content packs have been removed from powerbi.com and replaced with Power BI apps.
Any content packs that you have already installed continue to work. If you have previously installed a content pack and you want to update that content pack, you can download the .pbit files from either PartnerSource or CustomerSource between July 15, 2019 and September 1, 2019.
When you have downloaded the .pbit file, open the file in Power BI Desktop, connect to your Business Central or Dynamics NAV data, and publish the report to your Power BI workspace.
Note: The same parameters are used to connect to your data as you used in the content packs.
The Power BI apps are now available in Microsoft AppSource and function in the same manner as the content packs. The only difference is that you must have a Power BI Pro license to install a Power BI app. Once the app is installed, it can be shared with any user, regardless of license.
