This Power BI report provides the DAX reference \ Cheat sheet. This report extracts the data from the Dax references from the below MSDN link. The Web Data source and Add tables using using Examples has been used to create the report.

Hope this report provides a comprehensive view of all the available DAX functions. The cool part is when refreshed it will bring the newly added DAX functions as well in future.

It's not working anymore

For those that are looking for the upgraded version of this report, please look into this attachment. 

Do note that lots of modifications are made to the previous M codes & CSS selectors to fit the current documentation's HTML structure including changing the code logic to optimize query performance. Remarks & Examples (plus Return section) for each DAX functions are NOT working properly as another tables & data source are needed to collect these contents in order to flatten those into a record for the visuals. Due to bad performance of loading these web content with Power Query, these issues are not fixed and will not be fixed as using scripting language such as Python can scrape and transform these data faster and possibly optimizing anything for this report. Therefore, I would recommend to scrape the data separately with other tools and write to a csv file etc., then source to Power BI report. Note that refreshes might take more than 1 hour depends on your internet and resources. Nonetheless, feel free to take ownership of this report and make any changes as needed to fit your appetite.

BEST,

The web scraping function in this report has stopped working, as Microsoft has been re-structuring its documentation pages. I've attached a screenshot of the error message I get when I try to load the page where the report currently looks for its data.

I would love to have this working again. Any pointers on how to fix it?

 Hi,

This is reqally great, thanks for sharing it. However, when I press 'refresh', while there are no errors encounted, all the data in the two tables disapears (see screen shot below). When I press 'Edit Query' prior to refresh, there isn't any data in the tables there either. 

I am using the December 2018 version of PowerBI desktop. 

Any help would be appreciated! 

Cheers,

Alice

This is awesome, the refresh isnt working btw...

[msornakumar]

Thanks for the feedback. Can you please check if you have the latest version of the Power BI desktop installed in case if you are refershing from the desktop ?

[oscarg]

Yes I got the latest August version installed...

[msornakumar]

Hi ,

In Options --> Preview Fetures , Please make select the "New from Web Experience" and restart the Power BI desktop.

Thanks

Hi Sorna,

Once again I tried to update the file to include the new DAX formulas that were just released and I got the attached error. I think the problem is that the the URL for this new functions is as follows: https://msdn.microsoft.com/en-us/query-bi/dax/norm-dist-dax

So it includes the standard DaxFunctionWebPath but the DaxFunctionName is not DaxFunctionNameFormatted: 

norm-dist-function-dax

Neither DaxFunctionNameFormattedWithoutDax:

norm-dist-function

But rather something like DaxFunctionNameFormattedWithoutFunction:

norm-dist-dax

So how can we change the function GetDaxFunctionDetails to accomodate three possible scenarios using:

DaxFunctionNameFormatted, DaxFunctionNameFormattedWithoutDax or DaxFunctionNameFormattedWithoutFunction

= try GetDaxFunctionDetails([DaxFunctionWebPath],[DaxFunctionNameFormatted] ) otherwise GetDaxFunctionDetails([DaxFunctionWebPath], [DaxFunctionNameFormattedWithoutDax])

Any help would be greatly appreciated, thanks!

[msornakumar]

Hi ,

  Have fixed this issue by having a nested try block as below

try GetDaxFunctionDetails([DaxFunctionWebPath],[DaxFunctionNameFormatted] )
otherwise
try GetDaxFunctionDetails([DaxFunctionWebPath], [DaxFunctionNameFormattedWithoutDax])
otherwise GetDaxFunctionDetails([DaxFunctionWebPath], [DaxFunctionNameFormattedWithDax])

Thanks

Hi Sorna,

Was wondering if the pbix file you uploaded has this fix included or not?

Kristian

[msornakumar]

Hi Kristian ,

  Yes the Pbix file has the fix for the issue. Are you facing any other errors ?

Thanks

Sorna

Hey,
I didn't experience any issues refreshing the list on my desktop, but I noticed it didn't import all the new functions found in the list under "new DAX functions", at least combinevalues and the UTC ones. I wonder if they haven't added those to the main reference list maybe?

Kristian

[msornakumar]

Yes Kristian , you are correct. Those functions are not added under the main list and hence not picked up in the report.
