Modelling tab not working

[Anonymous]

Hi,

I have a report in which I want to show the data labels in a diagram as percentage of total. If I understand correctly I need to go through the Modelling Tab to do this. 

My problem in that when I click on the Modelling Tab, all buttons are unclickable... 

Also (perhaps unrelated), on the left hand side I have only a single option - the Report button. In many other screenshots I have seen there seems to be a couple of more alternatives, for example Data? 

I would greatly appreciate help and/or feedback regarding this.

Best regards,

Jonathan

hi, @Anonymous 

You are using live connections in this report.

https://docs.microsoft.com/en-us/power-bi/desktop-directquery-about#live-connections

For this connection, you could directly connected to the data model, so all these modeling processes could be done in the basic data model.

here is the document for you to learn

What's the data source and method of connecting?

And is this a new thing? Is it particular to this report?

Can you connect to a local test Excel file and use powerbi as normal (for testing)?
