Context Transition in Power BI and Tricky Examples

[@ritumaurya8162]

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.

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.

[@aijaz4441]

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!!!

[@toirshad]

Most tricky concept in DAX I ever felt... very well explained 👍

[@kayliedoe2312]

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!

[@GoodlyChandeep]

Thanks Kaylie, glad it helped. I made another one on Context Transition here - kzbin.info/www/bejne/hJy8qKqYbK5meLs Cheers

[@TheCraigie007]

Tricky Example Number three was beautifully explained.

[@alterchannel2501]

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❤

[@harfshortshayari3340]

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 :)

[@tersit89]

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 😂

[@mertols]

By far the best explanation of the most advanced concept of DAX. Thank you.

[@alex...g]

Everybody is different, but your teaching style lines up perfectly with my learning style and has been a great help to me. Thanks for your hard work Chandeep!

[@GoodlyChandeep]

Thanks a lot Alex

[@namangarg7875]

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.

[@GoodlyChandeep]

Thanks Naman :)

[@GoodlyChandeep]

Thanks Ankush :)

[@rantaleksi7086]

Great and elaborate yet simple enough explanation for this confusing subject. I feel like I finally have a clear idea how context transition works.

[@GoodlyChandeep]

Very very good explanation! Thank you...

[@GoodlyChandeep]

Glad you like it 😊

[@KgasS]

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.

[@GoodlyChandeep]

Yes💯!

[@bharatgarg07]

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.

[@SirTupsAlot]

Great explanations! Thanks!

[@luizkrein]

The last example I had in my work today was exactly like this one!

[@brundleseth51]

Genial, esos ejemplos bastante ingeniosos, especialmente el último

[@GoodlyChandeep]

¡Me alegro de que haya ayudado!

[@Obizzy8]

Crystal clear!

[@Magmatic91]

very good explanation !

[@dirkstaszak4838]

Super explanation. One question though. Why would Giuseppe use the measure in the sumx instead of value column?

[@kalinduSekara]

Excellent lesson Chandeep

[@pritipatil4516]

Thanks its clear sum and sumx difference

[@keerthihulagur55]

Great explanation

[@hugoderek50]

Very well explained many thanks

[@GoodlyChandeep]

Glad it was helpful!

[@BraulioPatriota]

Nice explanation!

[@emanueledelzoppo5164]

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!

[@shubhampipada3130]

@Goodly, so in the last example you showed of SUM and SUMX with SUMX doing the context transition, if I am not wrong, if we apply VALUES(Test Table) which would result in unique column values and then apply SUMX should work right?

[@Travel-Costa-Rica]

Great explanation as always...

[@chengwang411]

Perfectly put. 👍

[@cblondhe]

Amazing explaination ! Thanks

[@GoodlyChandeep]

Glad you liked it

[@cblondhe]

No one explained so explicitely. The value of the row becomes a column filter..........

[@MucahitKatirci]

Thanks for the video

[@ricardo8500]

Thank you, sir.

[@malchicken]

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.

[@suryac3462]

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!

[@RyanReynolds89]

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.

[@brij26579]

Very Well Explained 👌👍

[@GoodlyChandeep]

Thank you!

[@sqllearning7663]

I use Summarize function to summarize transactional table before using Iterator function It works 😁

[@raviranjansingh5527]

as i am student i am not affordable to this prices .thanks sir

[@maryamchavoshi6523]

Thanks For the video. How can I get the data set that you used in this video?

[@ramakumarguntamadugu1299]

Great explanation.. Keep it up 👍👍👍

[@GoodlyChandeep]

Thank you!

[@thedatapros5221]

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.

[@need2knowtamil249]

Awesome 👍👍👍

[@ssomtom]

Great. Thx.

[@MahadiHasan-qk5ko]

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.

[@bhaskarsubbaiah6002]

Hi sir, In this lecture you told to create the virtual table using values function to get aggregated sales per day with the distinct Calender Date. But that virtual table is not in the data model so how it will change with the Initial filter context on the calender date. Please help?

[@sandeepreddy7687]

Thanks Chandeep for detailed explanation.

[@gabionindia]

Awsomeeeeeeeeeeeeee!!!!!!!!!!

[@franciscoisaacs881]

Hi Chandeep, can't thank you enough for your contribution to the BI community. Your explanations are spot on and easy to understand, you are what all teachers should aspire to be. Quick question, Calculation Groups, is that part of your DAX course or have you posted a video on KZbin about that? Will register for your course as soon as I'm able to, quantity content such as yours does need to be paid for. Keep doing what you're doing brother!!!!

[@GoodlyChandeep]

Thanks Francis, I have not created an explicit video on Calculation Groups but I have used them to solve problem in various videos. I think it's time to add them to the course and make a few video exclusively on CGs. Thanks again!

[@alfonsorodriguezsandias8142]

Hello, thanks for your video. How could I know the date, the day, that the maximun sale is achieved?

[@GoodlyChandeep]

Write a measure something like = CONCATENATEX ( TOPN ( 1, Calendar, [Total Sales] ), Calendar[Date], ", " )

[@alfonsorodriguezsandias8142]
