Difference between CALCULATE(m, x=red) vs CALCULATE(m, KEEPFILTERS(x=red))

问题 What is the difference between CALCULATE(m, x=red) and CALCULATE(m, KEEPFILTERS(x=red)) Apparently they are not the same. I found docs and explanation but I still do not get it. https://docs.microsoft.com/en-us/dax/keepfilters-function-dax https://dax.guide/keepfilters/ 回答1: It is helpful to understand a bit more about how simple predicates in CALCULATE are evaluated. The following two expressions are equivalent; in fact, the first is just syntactic sugar for the second - the former is

DAX conditional sum of two columns with different granularity

This is follow up question of the one asked here . However this time two columns have different granularity and are located in different tables. So simple SUMX solution proposed earlier is not applicable. I attach SumDifferntGranularity.pbix file. How to construct a DAX measure which returns sum of either BudgetProduct (if possible) or BudgetBrand. The logic is take Brand if Product is empty. So expected results looks like this: +---------+-------------+---------------+-----------------+ | Manager | BudgetBrand | BudgetProduct | Expected result | +---------+-------------+---------------+------

Suppose I have a table as follows: TableA = DATATABLE ( "Year", INTEGER, "Group", STRING, "Value", DOUBLE, { { 2015, "A", 2 }, { 2015, "B", 8 }, { 2016, "A", 9 }, { 2016, "B", 3 }, { 2016, "C", 7 }, { 2017, "B", 5 }, { 2018, "B", 6 }, { 2018, "D", 7 } } ) I want a measure that returns the top Group based on its Value that work inside or outside a Year filter context. That is, it can be used in a matrix visual like this (including the Total row): It's not hard to find the maximal value using DAX: MaxValue = MAX(TableA[Value]) or MaxValue = MAXX(TableA, TableA[Value]) But what is the best way to

PowerPivot DAX - Dynamic Ranking Per Group (Min Per Group)

戏子无情 提交于 2019-11-29 14:06:55
I am searching for a method to utilize within Microsoft PowerPivot 2010 that will allow me to perform dynamic ranking that will automatically update the associated rank value based on filters and slicer values that are applied. Thusfar, all examples I have seen utilize the Calculate() DAX function that overrides existing filters within the PowerPivot table via the All() function which causes predefined filters that users may apply to be disregarded. To illustrate my requirements, please reference the example below: (Source Data within PowerPivot Window:) ---------------------------------------

Finding cummulative sum of MAX values

允我心安 提交于 2019-11-28 14:32:20
I need to calculate the cumulative sum of Max value per period (or per category). See the embedded image. So, first, I need to find max value for each category/month per year. Then I want to calculate the cumulative SUM of these max values. I tried it by setting up max measure (which works fine for the first step - finding max per category/month for a given year) but then I fail at finding a solution to finding cumulative SUM (finding the cumulative Max is easy, but it is not what I'm looking for).

DAX running total (or count) across 2 groups

拟墨画扇 提交于 2019-11-28 14:09:33
I'm very new to DAX and PowerPivots. I am using PowerPivot to pull data from an SQL server. The data I'm working with is pretty large and complex but I'm considering a simplified version of it for this question. Let's say I have 2 columns, one that contains product names and one that contains a date that product was sold. I have a row for each time 1 unit of any product is sold. Product | Date Orange | 08/13/2013 Orange | 08/13/2013 Orange | 08/13/2013 Apple | 08/14/2013 Apple | 08/16/2013 Orange | 08/17/2013 Orange | 08/17/2013 I want to use DAX to get a running count of how much of a product

I have a data set that resembles the following: Year Location Type Amount 2015 West Apple 12 2015 West Pear 14 2015 East Apple 55 2015 South Orange 62 2015 West Orange 64 2015 East Banana 12 2015 North Banana 23 2015 East Peach 43 2015 East Apple 89 2015 West Banana 77 2015 West Orange 43 2015 North Apple 2 And I need it to be summarized to show TopN as well as all other in order to keep the grand total the same. Just filtering to show only the TopN reduces the grand total and will not work... The end result should look like this (n=3 in this example): Type Amount Orange 169 Apple 158 Banana
