Meagan Longoria shows how to document a tabular model using Excel and Power BI:
The Database Info tab uses cube functions to display the values shown. The rest of the tabs use pivot tables and slicers.
You can download and use this model if you have Excel 2016 or 2013 with Power Query. Just download the file, change the values in the TabularInstanceName and TabularDBName queries, and refresh. I was able to open the file and update the queries with no issues and no changes in Excel 2013.
This is great if you just need documentation or a quick way to look up specific information. But we could really analyze this using visualizations other than tables in Power BI Desktop.
That’s pretty fancy. Check it out.
