Measure Dependency View (similar to the Query Dependency View)
The newly introduced Query Dependency view is phenomenal but what we really need is a Measure Dependency view. Here is what it might look like: http://ppvt.pro/2eXKndh
And a video detailing this idea: https://youtu.be/sYjBB_Ef66M
In one of my production models I have 60 Queries, but I have 200+ measures! I believe that is typical; usually I build Queries and Measures as lego blocks, combining simpler ones into more complex ones needed in the end. In fact I needed it so badle that I attempted to build a Measure Dependency view using NodeXL. While that works, it's a lot of heavy lifting. How cool would it be, to just click a button on Power BI Desktop and see all your measures in a Dependency tree!

With XMLA endpoint on Power BI datasets (Premium), you should be able to get the dependencies using a query like this:
SELECT * FROM SYSTEMRESTRICTSCHEMA ($SYSTEM.DISCOVER_CALC_DEPENDENCY, [KIND] = 'NAMED_DEPENDENCY')

Avi, great idea. I posted the following before I saw that it was a very similar suggestion...
Measures that reference and depend on other measures can be difficult to trace and debug. To make this easier, provide the option in the field list to show the measures that are referenced by other measures. This should be optional and performed individually for each measure to avoid unnecessary performance overhead. Here's a conceptual mockup:measure dependency (on my blog here: sqlserverbi.blog/2019/08/06/power-bi-product-suggestion-show-measure-dependencies/ )
Definitely need this on Measures.
This kind of functionality is crucial for building complex reports!

More than a year later and this is still the best tool out there https://github.com/otykier/TabularEditor

Great idea, where is it?!
Impact Analysis, dependency, data lineage - all about tranparency into the data, understanding and trusting the data used in analytics. Enhances users' ability to create robust, meaningful analytics and drive business conversations and decisions.

Once we have the dependencies, they should also be used when it comes to updating calculated tables/columns after changing e.g. a measure.
Changing a measure should not trigger a recalc of a calculated table where that measure was not used at all // has no dependency to

It looks great.

An addition to this idea is not only to view the dependency tree for the calculations, but also to view the visualizations dependent upon a measure. This would be extremely helpful for testing if a calculation changes and you need to regression test all the visuals within a workbook which contain those measures. This would also be helpful in getting rid of measures that are not used in your workbook
This could work similar to the "View Dependencies" right click menu selection in SQL Management Studio where you can see the tables, view, triggers, functions, and stored procs that are dependent upon the object or all of the tables, view, triggers, functions, and stored procs your object is dependent on.
And while we're at it could we have a Visuals dependency view as well?
It looks great.
Can you share the source for the recursive function ?

there is a third party software that support that

I did a recursive function for build a dependency tree for each measure. Look at the result:

This ia great idea when you develop a model!!! But there is another one, when you explore a model. Create Calculated Fields groups in the fields tab. When the number on calculated metrics increases it is almos impossible to remember the measures you already have. The filter helps but is not enough. I would like to see something were I can group all metrics. Like this
Current Month Signed $
MTD Signed $
QTD Signed $
Variance to Budget (VTB)
Variance to Forecast (VTF)
Sales Forecasting Reliability
Forecast Accuracy %
In my model, just to describe the different status, steps and time calculations linked with one Company "Sales", I have developed more than 250 different calculated metrics. It is tough to see from dependency perspective, and from presentation perspective

Yes, Yes, and Yes. Necessity when you have a lot of measures in your model.
German Henriquez commented
Now that I have 16 measures I consider this necessary. But I can control it yet.
