I had been reading books/blogs and looking for the videos which explains context transition. So far, no one has explained better than you. Thanks a lot for this crisp clear video on context transition.
100%
I've read multiple DAX books and watched dozens of videos trying to learn context transition, and I still didn't get it, until I watched this video. You did an excellent job explaining a deceptively difficult concept. The parts where you repeated yourself actually helped a lot for me, because each time you said it the first time, I was still thinking "Ummm... I think I maybe understand it, but not sure." And then when you repeated it, I was able to compare what I thought in my head to what you were saying, and that's when it finally clicked. Some people might not like the repetition, but for me, it was absolutely necessary, and I think that might be why none of the other learning resources had managed to convey the concept successfully before now.
To get this concept right, it is necessary to repeat it multiple time in a video. On our part, we need to repeat the video multiple times to get it right!!!
Most tricky concept in DAX I ever felt... very well explained 👍
I'm in awe. THE BEST explanation of context transition I've encountered so far. Bought a book, watched multiple videos but still this was very tricky to understand. I'll re-watch this video when I get confused again. Cheers!
Thanks Kaylie, glad it helped.
I made another one on Context Transition here - czcams.com/video/NkYwwb7I3BY/video.html
Cheers
Tricky Example Number three was beautifully explained.
Great explanation, simple examples, bravo! While watching this I understood that i had already used this concept intuitively but didn’t fully understand how it worked 😂
Love the way you explained it !!! Thank you.
The best explanation I have seen so far. Thanks!!!
Thanks. Clearly well explained. Specifically, the example on the mock up data was an ‘aha’ moment 😀
Excellent!! The clearest explanation of iterator functions.
Great explanations! Thanks!
Best channel for DAX, PQ & PBI.
🙏
Brilliant, and very easy to understand. Thanks, it solved a big problem of today.
Excellent Content...Thank you so much for doing this
Best. Clearest explanation!!! Thank you!!!🎉
Chandeep, you are brilliant, fantastic. Thank you so much.
Excellent, Clearly well explained.
I would not say it's tricky but it is conceptually correct. When one of your measures is non-iterable it does the whole calculation once and then is applied to the iterable measure, then definitely result will be wrong. Thank you for great video :)
Beautifully explained. Thank you.
This is best explained video for understanding context transition thanks I was trying to learn it since so long finally got it keep making video U will rock....
Wohoo! Brilliantly explained bro!😎🙏
Great and elaborate yet simple enough explanation for this confusing subject. I feel like I finally have a clear idea how context transition works.
Glad that was useful 💚
By far the best explanation of the most advanced concept of DAX.
Thank you.
Great explanation. Thank you so much!
Thanks for the time and effort taken to explain this concept
One of the best videos on Context Transition, thanks for the explanation!!
Brilliantly explained with tricky examples nitty gritty of context transition
Superb explanation of Context Transition. Thank you!
Thanks sir way of explain .keep more video on dax fundamental .
Watched again, understanding getting better. 😊
A brilliant explanation. Thank you!
Simply Amazing ,Even Some Experienced people fail to explain the way you explained.
Crystal clear!
Wow !.. I have watched other context transition videos BUT i only understand now through your explanation.. very clear with examples/illustrations.... thank you very much ! I clicked then the subscribe button :)
Glad it was helpful! :)
Perfect. It helped me to know that every measure is wrapped around an implicit invisible CALCULATE function in Dax. That's why writing only SUM will not give the same result, you are not writing the same measure, because every measure starts invisibly with CALCULATE 😊😊 love your videos, they help me out a lot, thanks❤
amazing explanation, probably best on the whole internet
Great explanation as always...
this is insane video. Superb brother... Thanks so much for the video
Great explanation. Thanks
I really loved your explainations, especially on that ticky concept of context transition. Bravo !
Glad you love them!
Genial, esos ejemplos bastante ingeniosos, especialmente el último
¡Me alegro de que haya ayudado!
Perfectly put. 👍
Excellent lesson Chandeep
Best explanation ever. Thanks a ton!
You're very welcome!

Glad it was helpful!
thanks a lot this was bugging me since yesterday. Finally found an apt explanation.
Thank you so much! This is the BEST explanation. I've been struggling for a long time to understand this topic. God bless you!
Glad it was helpful 💚
Wow, that was an amazing lesson! Broke it down so well!
Glad you liked it!
Explain row level security briefly.. strong explanations, amazing and keep going👍👍
The last example I had in my work today was exactly like this one!
Thanks its clear sum and sumx difference
Wow Finally understood this 😮❤
Brother..no word to admire your explaning DAX..it is really final DAX destination...believe me it is coming from my heart....Bhai...your examples literally leave no confusion to understand DAX....I joined class and see explanation difference.........God Bless You bro...🙏🙏🙏🙏🙏🙏
Thanks Ankush :)
If a person has basic understanding of DAX, then I wud highly recommend to attend his course or vdos watever suits uhh... Because this person is teaching DAX with such a simple explanation. Big fan of Mr Chandeep.
Thanks Naman :)
Nice explanation!
Hi Chandeep, Thanks for explaining this concept in a very easy way.
I have a doubt here, why we didn't get the issue in the first example where we have multiple rows for a single date as we have in the second example.
very good explanation !
The best explanation of context transition on the whole of f***in youtube
Great explanation
easy to understand. thanks goodly
Glad to hear that Teuku!

Glad You like it 💚
Thanks!
Thank you, sir.
Great explanation.. Keep it up 👍👍👍
Thank you!
Very well explained many thanks
Glad it was helpful!
Nice explanation on context transition. I think for the Best Selling Day measure instead of using values function just the calendar table will also work as it always has unique values to iterate.
Yes💯!
brilliant !
Brilliant video AS ALWAYS!
I was just wondering if values(calendar[date]) could be replaced by values(sales[orderdate]). Is this makes any sense? And why/why not is necessary to use the function "related" when using a column of another table (in this case the calendar date). Hope you answer my question(s), many thanks!
Amazing explaination ! Thanks
Glad you liked it
No one explained so explicitely. The value of the row becomes a column filter..........
Excellent!
Thank you!
Very Well Explained 👌👍
Thank you!
That's Amazing .......
Thank you!
For [Total Sales] I wonder if the SUM function would work if a RELATED(?) function was used? I’ve read that measures and CALCULATE can take into account table relationships automatically I think, so I wonder if only the measure / CALCULATE work because they are able to bring in the relationship between Calendar and Sales table, while just the SUM by itself cannot unless it’s paired with a RELATED(?) function.
Super explanation. One question though. Why would Giuseppe use the measure in the sumx instead of value column?
Thank you
Thanks for your help
Happy to help!
good explanation .......bro
Thanks Suresh!
OH man, that is a really nice explanation for a normal human. I really appreciate it. One question, why DAX masters :) always use VALUES for ie. days table, where there are only single days in calendar table, so what for? This is what i really do not understand
In this scenario, the values was unnecessary!
The results would have been the same without VALUES as well.
Good catch :)
@@GoodlyChandeep thank You. This is SOO well explained.
Thanks Chandeep for detailed explanation.
thank you sir
Great
I use Summarize function to summarize transactional table before using Iterator function It works 😁
Nice Explanation
Thank you!
as i am student i am not affordable to this prices .thanks sir
Genious
Thanks for the wonderful explanation. I just have one question : If there was one more column added to the mocked-up data which enables each row to be uniquely identified, will we still be getting the duplicates? since only the column filter will be applied, I would expect that we would still get them. I am just a bit confused how in the second example, regarding the calculated column, each row is uniquely identified. Can you please elaborate?
Thanks a lot!
In case you’re still wondering this 7m later haha, I think I can help. If you add a column that creates a uniquely identified row, it would no longer duplicate the results and you would get the correct answer. The reason is because when Context Transition happens, now the new unique identifier column will be included in the resulting Filter Context, so it won’t pull in the other rows (such as the second row with Category A) and duplicate the results. It will be filtered to that single row and thus sum appropriately.
Hi Chandeep, great video.
but i have one doubt here. when you refere some measure in calculated column like you did for total sales, logically it should not break down. because though u refer measure its a calc column and it should understand only row context and row context disable all active relationships for that table.
i tried same now , but it's not breaking down. in video at 11:05 or so values are breaking down.could you please clarify this.
nice explanation
Thanks for liking!
Can you please start power bi series ?
Nicely explained. But I want to know if I want to write a measure for the maximum sales of July 2001, how to do that? I tried but it didn't work.
Thanks For the video. How can I get the data set that you used in this video?
