2. Open the file using Power BI.

I was following the guide at this link and it looked pretty simple, except for the fact that doesn't work.

I download the file DMA Reports V3.1.pbix and as soon as I run it asks for the server and database credentials.
I enter them and I load, here is where the problem starts:

Expression.Error: The key didn't match any rows in the table.
Details:
Key=
Schema=dbo
Item=ReportData
Table=[Table]

It looks like it's searching for something that is not there.
I do believe this Power BI file must be pointing to a specific database or set of information but this is not specified in your guide.

Explain, please

I now have it, I need to

1. Create DMAReporting and import data with this PowerShell script
2. Point the .pbix to DMAReporting.

That wasn't easy, there is no documentation.
What's the difference between DMAReporting and DMAWarehouse?
In what case I have to use one or another?
In which order I should process the scripts?
etc, ...

...we need documentation on the page
