Literally a lifesaver I have been messeing around with about a hundred measures, measued columns filters etcfor the past 2 days and this worked like a charm. THANK YOU!!!!
This video was incredibly useful! I was trying to figure out how to have a dynamic KPI visual that has a rolling 12 month graph based on date slicer selection and this did the trick. Thank you very much!
How did you manage to Solve the rolling 12 sum? When you say rolling sum, do you mean the rolling sum for each month or does the rolling sum only for the months that are present in the visual? 😊
This is a great solution! I'm using and it works very well, the only issue is if there is no value in a period, it will skip the month instead of showing 0, in a table the result is even worse with a missing month, but thank you anyway! 😎
I was wondering from past 2 days everyone explained but not explained every single steps to perform. Thank God you save my time and i got the solution now. Thanks a ton!!
Grazzie Alberto, for insurance loss ratio reporting with premium and claims and a loss ratio % this is an amazing solution. i spent most of the past 2 months trying to build this with a slicer and then trying to set dates back etc. i have stopped chasing, and can start implementing !!
This is wonderful. We struggle with Current month reports as using dates will hide PriorMth on the first few days of the month, where business wants to see PM sales until the day after the first Sales day to CurrentM. I do with the a [LastDayWithSales] measure & a binary date table calculated column as a filter. But this UX requires to unfilter the binary [Current month] filter then choose a date range. Your solution here is fantastic. Thank you so much
Thank you so much I've been looking for that for a loooong time and you are the first explaining it properly. Looks like i'm going to watch all your videos ;)
This is Fantstic Alberto!! Thank you for sharing! Very clear with excellent demonstration of steps and the (interim) results we should expect along the way. I have been looking for something similar (a 10 year rolling average) for a few weeks and you’ve answered a ton of my questions. I should be able to do what I need to now!!
Very grateful for this instructional video! It bugs me that PowerBI makes things that should seem so simple seem so complicated. In Tableau, things like this are accomplished in much less steps and with also very limited coding
Excellent video, so intructional and well-explained. Filter context is examined deeply and the reason for each filter manipulation becomes clear. This pattern will be certainly used with some modifications, thank you for this vid!
Thanks Alberto. Well explained and easy to implement. I have one issue though. I have noticed that if one or more months in my N period does not have data, that particular month is not shown in the chart. If I set "Show Items with no data" to ON, then it ignores the Previous N months to show filter and shows all months (months less than (current month - N months) and months greater than current month). Could you help?
Very good solution. Could i use this approach to show values from the first month of the selected year to selected month? For example choosing 2024 in year slicer and October in month slicer getting the values from January to October and show values in matrix visual, monts values in their own columns.
Excellent solution! I do have a question if you have a solution for if I for each month would like to show the sum of the Last 12 months i.e. like a trailing LTM for the last 12 months still only selecting a single month.
Thank you Alberto, DAX Champion. :) This Channel helps me a lot. You are champion on DAX and post o through with your channel i am trying to get all your knowledge I have one query
Great solution, I am using to show last 3 quarters for all my measures, but is it possible to show last 3 years YTD before the 3 quarters like this dynamic column based on user month enddate selection 2018-12,2019-12,2020-12,2021-03,2021-06,2021-09. Thanks.
Thank you for this tutorial. I tried to use this showing previous days, it worked but it is including weekends. How can I skip these days so it won’t show on the graph?
Thank you so much! I followed your steps, and it works like magic. However, I have one small issue. For example, I set the view to display last 12 months, but sometimes 1 or 2 months do not have any data. I still want to visualize those months. How can I achieve this? Please advise.
Excellent Explaining @alberto. can we group this to a Sales_Agent (Say) level ?. By following the approach in ethe video i'm able to get on a whole; when trying to break about at sales-agent level i'm able to see only the months when he made any sale; but looking for all the last 6 months even if there is no sale from him. thanks in advance
Thank you for such videos❤. Although I have some different scenario, I have YYYYMM slicer on my report page with multiple years of data.And data is loading on monthly basis. Currently I have saved YYYYMM slicer with recent 12 months selected but client is expecting if new month data gets loaded again recent 12 months should be automatically updated. Any input on this please.
thanks for great video. one more simple solution is just create a column in date table that return 0,1 if date column is less than 6 month from selected date.
Awesome Alberto!! Thank you for explaining it so clearly and providing step by step explanation. If I want to show '0' for all the blank COUNTS across the last 12 months, is it possible? I tried to include COUNT('Cases'[Number]) + 0 also tried IF(ISBLANK('Cases'[Number]) ), 0, ('Cases'[Number])) in the CALCULATE section, but it is displaying all the months and not giving only for the last 12 months data set. It is not giving me the desired output.
Hi Alberto - Thank you for sharing this training - I have a question how did you create your Date Table? I have used the Calendar option and it doesn't work. Could you share in your article how you created your Date Table to have this filter selection work.
Very Nice video. We have an almost identical case but in our case we use a month table that is related to the fact table. So the dim_month and fact table have a key yyyymm but also a endofmonth date. So If we want to do the same ss in the video we need to rewrite the Logic here. We want 12 month backward from a selected year month. Perhaps it is possible to get a date without selecting the period slicer like last date/period with data
I currently use a technique like this when providing financial reports, I am also having the data presented by our companies fiscal year and crop year to date CYTD and FYTD from the respective cost centers. The challenge I have is showing the "future" months as well to look at rolling forecast as well as total Budget. I dont use calculation group, and my model right now requires about 5 measures just to give me FYTD based on a current date or any date you wantto type in and it re-calculates the measures based on that date. Thank you for this video. Could you show how you would implement this, but in a companies fiscal year to date measure ( powerbi knows the first month of the fiscal year regardless of what date you set as input?). Thanks again.
Thank you for the wonderful explanation. love your all videos but my Date field hierarchy gets removed which is creating problem for slicer, Any solution on that?
I used field parameters (Mth/Qtr/FY) on Category of waterfall chart, and the out-of-the-box experience is that it would not show 'waterfalls' from beginning up to the first data point set on the axis/category. Eg. When 'Qtr' is selected, chart will plot 4 data points on the axis, and then draw 3 sets of waterfalls between the 4 points (duh~). The first set of waterfall to depict the movements from beginning of period up to the first data point would NOT be shown, contrary to 'normal user expectation'. Certainly not a bug here but it is such a wet blanket to not have easy to implement dynamic axis parameter on the waterfall chart. Thankfully the technique here enabled adding a period dynamically to the front of whatever periods have being selected to serve as a 'beginning' axis point. Thus when user select a year, the measure would consider 1 additional period prior user's selection. For details sake, the measure i used was a balance-todate that accumulates cash movement to show a balance at the last day of selected month. Hopefully this comment helps someone struggling with the same issue, particularly with waterfall chart.
But say I need to figure out the max and/or min date of the original date table (as selected) for the purpose of a measure inside the matrix. using this technique forces the context of the matrix dates on all calculations even if i use a VAR in the measure. How would I you suggest to extract the original date min/max context?
that's very helpful, thank you. HOWEVER. there's a big red warning flag you should mention, it caused me headaches : using group calculations not only REQUIRES you to not use automatic-measures on your visuals, or it will simply not work. But also, as soon as a group calculation is added to the model, automatic-calculations are no longer accessible for a new visual, requiring the user to ...... create a measure for every single data he wants to visualize !
@@SQLBI Hello, are you aware of any other solution for showing last x months based on user single slicer selection, please? I do not use total, but amounts diveded per category and for that this solution by copying date table unfortunately does not work
Hello Alberto, thanks for this very informative video! Just a question, you're displaying a calculated data in your example (Total Sales). I was trying to display volume (Distinct Count) per month to which I cannot implement the "CALCULATE" function. Would you be able to suggest what should I do?
I would like to create a view that shows previous 3 years data as totals and additionally the last three months as months. So for the last part I could use your solution, but how adding the three years to the graph, is there a smart solution for that as well?
Thanks for a great video Alberto! I was wondering if this could be used to only show data for every 6 months before a date for a past X amount of years? For example company A’s most recent date is 6/1/21 and looking to see sales on 12/1/20, and 6/1/20, but company B’s most recent date is 3/1/21 so sales 6 months from their date would be on 9/1/20 and etc. If not possible to use this type of example, do you have a similar video? Thanks!
Excellent video, thank you so much! wondering if you are able to share way to show the previous 3 months and future 3 months... where your selected value is the "pivot" column of the chart. For example, I'd like to be able to see the revenue targets from the past N months and also the revenue targets for the next N months.
Wait I didn't understand at 9:50min mark when you were debugging why you expected 184 rows. Can you explain that? Thank you in advance. Love the videos. Learned so much.
Hi, great video i've loved it so useful, i have a problem, eg : when i try to show the last 6months for march2020 it takes in consideration the months only so it shows feb,jan,dec,... for 2020 all of them.so i want dec,nov for 2019 how to solve this ?
Thanks for the video! When we click on the month axis, it will cross-filter other visuals on the same page. The cross-filtered visuals display incorrect result because the filter context from calculation group will be applied. Is there anyway to prevent this inside the code instead of manually disabling cross filter for each visual ?
This is a super video!! I implemented it as best as I could, however, the 6 months & associated values are showing correctly, however, I'm getting all of the other months also, but they are showing as zero. Any tips on what could be happening would be greatly appreciated.
I know this is a older video, but does anyone know what formula he used for the Year Month Number? I cannot get it to sort correctly. I feel I have spent more time on the sorting issue than the entire visual...
HI....... Can anyone tell me how to show last Six month sales with discontinue month & also I want to show a month which has no sales as a null in last six month filtering?
Hi I need to count 6 month data from prior month and I tried to use this Dax it don't work for me! I have two table Date and Date2.can you help me to find solution? thank you
Hi all, When I try to make the deactivated relationship between the two calendar tables (Many to one), my calendar tables loses the date format, so Time Intelligence is not working. In the video, after the relationship is created, both tables keep the date format but in my case, the format is lost. I can set manually one calendar table with Date/time column format but the second one, I am not able to do it. Anyone knows why is this happening? Thank you
Alberto you are my hero, One favor : how it is possible to put in the same chart the YTD value, the last 3 months, the last 6 WEEKS & the last WTD day by days.
This is the best solution for Rolling KPIs using a filter selection for month that I've seen. Thanks Alberto
I applied this solution using a Sparkline for a KPI Card. It's really helpful and useful for my company. Thanks Alberto!
Thank you. I love that you move through the example step-by-step to help us understand how the calculation works.

What about having a disconnected date dimension and use it for filter and use the date dimension in X axis of chart.
Do we have any option if in any month we don’t have any data we need to
Show that as well
