It's often useful to compare a figure with the equivalent figure in a previous year. For example, the figure for January shows up assince it's picking up the figure for the same time period 12 months earlier. I must admit I prefer this solution, since it's more generally applicable, the function name is shorter and I think it's easier to understand.
Outstanding course feedback Average score 9. Thanks for looking at our blogs! The same period in a previous month, quarter or year It's often useful to compare a figure with the equivalent figure in a previous year. The function gives the set of dates for the same period, but 12 months earlier. Add a specific number of intervals of the required type to the current set of dates. Argument What it means Dates The calendar dates corresponding to the pivot table query context.
NumberOfIntervals How many periods forward if positive or back if negative you want to go in time. The two measures compared the results are the same.

Natural gas.One of the more common calculations a company uses is the last twelve months, or LTM, of data. This can be tricky if your date table always has a full year of dates for the current year, which it generally should. So if today is March 3,my date table will have dates through December 31, This is usually necessary for the date intelligence functions in DAX to work properly, and companies may have data beyond today in their model.
For example, budget and forecast data will generally extend through the end of the year, or at least beyond today. However, it often is challenging when you are trying to hide these future dates for specific measures. Marco Russo recently wrote an excellent post on hiding future dates or calculations in DAX. The concept is brilliantly simple.
I needed to create dates that were in the previous 12 calendar months, and I was working with a Power BI Dataset, which is a Live Query, and you cannot add columns to Live Query models. So I opted to create two measures. First, I needed to create the date logic in my dates table.
I wanted the previous 12 full calendar months, not the last days of data. StartDate - This calculates the month 12 months prior to the EndDate, then adds one day to move to the first day of the next month.
It will do the for the entire month of March. Side note: Use double pipes to allow multiple conditions for OR logic. Condition1 condition2 condition3, as OR is also restricted to two conditions. Now I needed to calculate sales for LTM. I already had the [Total Sales] measure below:. However, this measure is both a bit more complex, and if you wanted to have other LTM measures, such as units sold, or cost of goods over the last year, dollars purchased, etc. Well, iterator measures do, but they have to have row context to start with.
They cannot create it out of thin air. You also cannot use measures in slicers or filters in your report. For those, you must use either a calculated column, or bring the column in through Power Query.
Take advantage of the Recent Sources menus to avoid typing, or even get a bit of help remembering where some of your data is coming from. Quickly rename query steps, even if Power Query is still processing data.

My filter context contains all dates in a financial year eg. I would like to calculate sales for the most recent full month in the selected financial year. For the current financial year 1-Jul - Jun, I would like to calculate total sales for August, since it is the most recent full month in the period as of today Sep I have tried the following:.
This is not allowed. Since today is 16 Septemberthe most recent full month was August You could also use this to set up a measure, instead of a column, and you can use it in your PowerBI dashboard like with this card:.

Triage needs to be fixed urgently, and users need to be notified upon….I'm trying to find a way to filter out last caledar month's data from the rest of the data and I need it to work automatically when the year changes.
In other words, any time I look at the table, I want to know which rows of my table represent data from the last calendar month. For example, if looking at the data today, July 12, I want to know which data belong to the month of June I have a calculated column named DecisionDate that contains dates spanning across the last decade. This is the column I'm trying to filter on.
Go to Solution. I just posted this for another thread that was looking for something simular. Hope it helps! View solution in original post. You could use the Relative Date Slicer, in which you could then select the "Last" "1" "Months Calendar " which would then show you your data for the previous month on your report. Have you tried the solutions provided above? If it works, could you accept it as solution to close this thread?
If you still have any question on this issue, feel free to post here. Thank you! This worked though.

Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. This works fine. I have tried the following so far. Both return the same answer which is total for the entire previous month. If I simply hardcode the start and end date in datesbetween version above, then I do get the desired result.
But that is not the solution. Kindly assist what I am missing out on and how I can get Previous Month year to date total. If you're aggregating at the month level i. Novemberthen the measure you have above will show you the entire month of December compared to the entire month of November and since December is a partial month and November isn't, it causes the mismatch you see.
If you filter to the current date e. Assuming you don't want to filter to the day level not unreasonableyou could enhance your formula to filter out future dates. For example:. This says, if the date is after today, don't pass it into the TOTALMTD calculation so it will only calculate the first 7 days of the month, for example, if today is Dec 8th - even if you're looking at full months on your report.
Side note: you can also write your previous month measure to re-use your MTD measure rather than redefining it. Learn more. Asked 3 years, 4 months ago. Active 1 month ago. Viewed 8k times.
