Previous month % - error
Hello, I'm trying to calculate previous month difference % in the attached dashboard. As you can see, the previous month function does not work properly at all and shows strange percentages. Sometimes % is missing etc. Does anybody know what I'm doing wrong? Can somebody help please? I'm attaching PowerBI Desktop file: https://drive.google.com/file/d/1MR9BP7BwVnnF_pH26VqLhHfNwVaTLTqF/view?usp=drive_link
Dynamic % Difference Dax when filtering on non consecutive years
Hi there, I have a matrix in power BI, items in rows, years in columns and a YOY% difference measure. I can;t show actual data, so here is an example in excel of what I'm doing: Problem is I'm not always comparing to previous year. Sometimes we may want to compare 2019 Vs 2022. This works in excel: Excel calculates the difference in the filtered period. However when I do this in Power BI, when I filter it returns the previous year % difference not filtered period. In power BI I am using a matrix like this: Fruit YoY% (from quick measures) code is: Fruit YoY% = IF( ISFILTERED('Date Table'[Date]), ERROR("Time intelligence quick measures can only be grouped or filtered by the Power BI-provided date hierarchy or primary date column."), VAR __PREV_YEAR = CALCULATE( SUM('Fruit'[Value]), DATEADD('Date Table'[Date].[Date], -1, YEAR) ) RETURN DIVIDE(SUM(Fruit[Value]) - __PREV_YEAR, __PREV_YEAR) ) Which works for YoY, but when I filter, eg, 2020 Vs 2022, it still shows 2022 Vs 2021 % dif. When I use the below code, it works when two filters are on, but defaults to 2019 Vs 2022: Fruit Earlier = VAR earlieryear = calculate( min ('Date Table'[Year]), allselected ('Date Table')) return calculate ([Total Fruit Sum], all ('Date Table'), 'Date Table'[Year] = earlieryear) Fruit Later = VAR lateryear = calculate( max ('Date Table'[Year]), allselected ('Date Table')) return calculate ([Total Fruit Sum], all ('Date Table'), 'Date Table'[Year] = lateryear) fruit % dif = var lateryear = calculate (max('Date Table'[Year]), allselected ('Date Table')) var maxyear = max ('Date Table'[Year]) var earlier_ = [fruit Earlier] return if (lateryear = maxyear, divide ([fruit later]-earlier_ , earlier_)) Ideally, I'd need top level to be YoY%, (across all years if possible but 2022 Vs 2021 would be fine), then the slice the years to get the below: So ideally it would be: 1. YoY% difference (2022 Vs 2021, 2021 Vs 2020 etc) 2. Slicer two years (eg 2022 Vs 2020) 3. Filtered years % difference eg 2022 Bs 2020) 4. Remove slicers to return back to YoY% difference (2022 Vs 2021, 2021 Vs 2020 etc) Any help on what DAX I need to make this work would really help!
