Thanks for this article/video Marco. Filter context can be complicated, even for expert Dax developers. Articles like this are a must, getting back to the basics.
Thank you very much for the content. I believe that many of us who work with BI understand it better when it is explained visually. Screenshots, calculated results and drawings are quicker to understand than long tutorials in real time. For more videos like this! Thank you for this gift!
What an awesome graphical explanation of Filter context. Key is the Initial context and then the Target context and then using the correct CALCULATE measure
Cheers sqlbi team, these explanations are mind-blowing. All the time in my bi journey, i could make sense of the actions behind the scenes of the filter context but felt hard to contemplate. Today it's head on.
Really like the new way you presented in this video. The visuals make things very clear and easy to understand. I hope you can do more videos like this in the future. All your videos are good, but this could be even better.
Let's not forget that if the year used from a calendar dimension table is sorted by some other column of that table, also this sorting column is part of the filter. I learned this lesson in the hard way 😢
Nice video... great content .. Thanks.. in the last example data from net price 600 to 999 will it appear or get filtered.. if not please provide the explanation
Great explanation as always Marco. What is the reason in case I want to calculate sales amount that is not blue, but want to use color slicer and that gives me a static value and not filtered by the color slicer. Not Blue Measure = CALCULATE([Sales Amount], 'Product'[Color] "Blue"). I had to use KEEPFILTERS or FILTER in order to work and use the slicer. Thanks!
This video shows how to make changes to filter contexts, but how do we know what the initial filter context is? Is it always explicitly defined in a measure? I'm concerned certain visuals or default summarization settings implicitly define contexts that can't be easily seen by clicking measures and seeing their dax formulas. For example if i come across a visual, shoui ld look in the fields to find definitions of measures to understand the starting context? How to make sure all existing filters are accounted for exhaustively? What other places can they exist in? (This video shows filter pane is a source of existing context too) For overwriting/keeping contexts does it propagate through the entire lineage of definitions? For example 16:06 shows Bnechmark 2017 measure depends on another measure Sales 2017 which depends on Sales Amount.
The purpose of DAX is to enable writing measures that work in any context. You can explore the filter context for debugging purposes with the debugger integrated in Tabular Editor 3, or by creating a special measure in the tooltip (DAX Studio has a feature to create it automatically) as described in www.sqlbi.com/articles/displaying-filter-context-in-power-bi-tooltips/
How do you filter a virtual table inside a measure using a selectedvalue from a disconnected slicer? The filtered table returns no data - as if the selectedvalue were returning multiple values - but it is not! If I put a default value in the selectedvalue variable it works as expected, and likewise if I return just the selectedvalue variable - it dynamically shows the value selected in the slicer. Yet the selected value doesn't seem to be recognized when used to filter the virtual table. Help!?
SELECTEDVALUE returns a single value, you should use VALUES to get all the selected values. Indeed, SELECTEDVALUE internally uses VALUES; as described in dax.guide/selectedvalue/
me costo un poco seguir el video ya que lo veo con subtitulos en español, asi que lo repeti y detuve hasta entender un poco... seria muy bueno que se pudiera traducir los videos a diferentes idiomas. Saludos desde Colombia.
Should we always use KEEPFILTERS? My question is based on the assumption we cannot control if an user adds an external filters, for example just for filter a location or an year... if in our measure we use the "same filter", we overwrite the user filter... so isn't it safer to always use it?

Visually representing the Filter context is a great way to understand the filter/data flow. Thank you for the great explanation.
Love those visual representation. Truly a picture is worth a thousand words. Combined with clear and precise explanation. Priceless.
This is such an spectacular explanation. You are a fantastic teacher. Thank you!
Thanks for this article/video Marco. Filter context can be complicated, even for expert Dax developers. Articles like this are a must, getting back to the basics.
Accidentally discoverd this Channel. I'd say that the in-depth explanation of how DAX work is excellent ! Thank you very much for you work ! 💐💐

As always you videos are blessing for people like me who are starting to learn and really understand DAX better. Thanks ❤
I still get wrapped around the axle sometimes when it comes to filter context. This video helped to clear a few things up.
Thanks.
Clearest explaination for this concept I have ever seen! Thanks guys, this is great
You don't know how much I needed this video at this particular moment!
Cheers sqlbi team, these explanations are mind-blowing. All the time in my bi journey, i could make sense of the actions behind the scenes of the filter context but felt hard to contemplate. Today it's head on.
Very clear explanation of an often bypassed topic by beginners. Excellent content as always!
Wow. I never comment on videos, but this one was actually very, very helpful. Yes. More colorful, simple visuals to convey complex info. :) Kudos!
Absolute legends! This is a wonderful resource to learn from and especially to share with new developers!
Really like the new way you presented in this video. The visuals make things very clear and easy to understand. I hope you can do more videos like this in the future. All your videos are good, but this could be even better.
The visuals (Whiteboard) really helped, thanks!
Fantabulous way to explain filter context. Love it
This is beatiful. You are stepping up your visauls game. Way to go, looking forward to more!

Un video spettacolare... Marco spiega in modo magistrale¡¡¡
Finally the so waited pedagogical paradigme shift from Sqlbi
Most awaited video. BDW I have read your DAX book. Thanks❤
Thank you so much, it helped clear up a lot of confusion about filters.
great video! please, keep doing these visual representations.
Thanks for such a detailed explanation! Very useful and interesting.
Filter Context NOT a myth anymore. #SQLBI team never disappoints us.
Thank you very much Marco. Fantastic explanation as always 😄
what a great explanation, Thank you
Nice explanation. Can we have row context and context transition videos in same format.
Thank you
Coming in July/August!
Nice video... great content .. Thanks..
in the last example data from net price 600 to 999 will it appear or get filtered.. if not please provide the explanation
Great video !!! Thanks for sharing, Marcelo, Buenos Aires, Argentina
Ottimo lavoro, come sempre!
Marvellous explanation! Many thanks!
Thanks. Enjoying DAX.
Nicely done Marco
Awesome explanation. Loved it.❤❤
Brilliant explanation!
Very nice video and well produced
Brilliant tutorial, thanks!
Amazing explanation. Thanks!!

Well explained sir!!! Thank you!!
Wow, I think I might actually kinda understand this concept now. 😅

Phenomenal
Fantastic!

How do you filter a virtual table inside a measure using a selectedvalue from a disconnected slicer?
The filtered table returns no data - as if the selectedvalue were returning multiple values - but it is not! If I put a default value in the selectedvalue variable it works as expected, and likewise if I return just the selectedvalue variable - it dynamically shows the value selected in the slicer. Yet the selected value doesn't seem to be recognized when used to filter the virtual table. Help!?
SELECTEDVALUE returns a single value, you should use VALUES to get all the selected values. Indeed, SELECTEDVALUE internally uses VALUES; as described in dax.guide/selectedvalue/
why is the sum of the various amount for the colors not equal to the contoso amount

We evaluated that, but it's too expensive for now. TH-cam will likely implement not too far in the future.
I didn't quite understand the last example. Are the net price items with value above 600 going to be used in the calculation?
No, because all filters (the orange one and the blue one) are active at the same time.
Should we always use KEEPFILTERS? My question is based on the assumption we cannot control if an user adds an external filters, for example just for filter a location or an year... if in our measure we use the "same filter", we overwrite the user filter... so isn't it safer to always use it?
It depends, see www.sqlbi.com/articles/best-practices-for-using-keepfilters-in-dax/
@@SQLBI Thank you!
Row context visually please 😂
Coming in July/August!
Tchau
Not clear
