I have a measure defined in a cube like
Sales = CALCULATE(SUM(FactSales[Amount]), FactSales[External] = TRUE())
In PowerBI I would like to override the filter on the External column. I've tried
All Sales = CALCULATE([Sales], ALL(FactSales[External]))
But ALL(<column>) only seems to work for context filters.
Is there a way to override the DAX filters as defined on the measure in the cube? using DAX.
My understanding is that you've applied the filter within the [Sales] measure already, so when you define the ALL function, it will only apply to external conext as you've said.
Try this?
All Sales = CALCULATE(SUM(FactSales[Amount]), ALL(FactSales[External]))

All of the measure that I want to cumulative has the same formula. So, is there any way to use the thing like function or any thing in calculate measure to resolve this issue?
There are two ways to achieve your aim:
1- the first solution is based on using the business intelligence wizard to add time intelligence to your solution.
The time intelligence enhancement is a cube enhancement that adds time calculations (or time views) to a selected hierarchy. This enhancement supports the following categories of calculations:
List item
Period to date.
Period over period growth.
Moving averages.
Parallel period comparisons.
The wizard will let you chose the calculations and measures you want to apply.

2- Use a dimension table to calculate your calculations, this solution is more complicated, but very powerful and one of the best practices.
The first step is to create a new physical dimension, with real
members for each of the calculations we're going to need. We don't
actually need to create a table in our data warehouse for this
purpose, we can do this with an SQL view like this
CREATE VIEW DateTool AS SELECT ID_Calc = 1, Calc = 'Real Value' UNION ALL SELECT ID_Calc = 2, Calc = 'Year To Date'
Next, we need to add this view to our DSV and create a dimension based
on it. The dimension must have one hierarchy and this hierarchy must
have its IsAggregatable property set to False. The DefaultMember
property of this hierarchy should then be set to the Real Value
member. Giving this dimension a name can be quite difficult, as it
should be something that helps the users understand what it does –
here we've called it Date Tool. It needs no relationship to any
measure group at all to work.
Our next task is to overwrite the value returned by each member so
that they return the calculations we want. We can do this using a
simple SCOPE statement in the MDX Script of the cube:
this code let you create the YEAR-TO-DATE aggregation for all your measures.
SCOPE ([Date Tool].[Calculation].[Year To Date]); THIS = AGGREGATE ( YTD ([Date Order].[Calendar].CurrentMember), [Date Tool].[Calculation].[Real Value]); END SCOPE;

is there a difference between a native cube measure (for example Measure1) and this mdx measure :
Measure2=[Measures].[Measure1] ?
Because when I use these measures together I dont get any results, and when I use them one by one I get what I want.
So the Cube Measures are present at the time of cube processing where the "MDX measures"(correct name is calculations) are determined at the query time. You should try to use the Cube measures where ever possible.
Secondly they can be easily used together.
I am new to SSAS. I have a requirement, I need to calculate no of working days between user selected date range (either in Excel or SSRS or PowerBI). I found the MDX query, I need assistance with create a named calculation with MDX expression.
Date Dimension (Filtered):
MDX:
WITH MEMBER Measures.WorkingDays AS
COUNT
(
exists( EXISTING {[Dim Date].[Date].[Date].members}
, [Dim Date].[Is Weekday].&[1] )
)
Select {Measures.WorkingDays} on 0 ,
[Dim Date].[Month].[Month] on 1
from [Project Cube]
where ([Dim Date].[Date].&[2018-01-01T00:00:00]:[Dim Date].[Date].&[2018-04-25T00:00:00])
I need to add this named column on Fact table as measurement. I am having trouble with the below items:
Creating named query with MDX expression mentioned.
Adding a [Number of Working Days] as measure in Fact table.
Please correct me, If I am doing it in wrong way. My requirement is I need a [NoOfWorkingDays] as measure in fact table, so that I can use SSAS aggregate to use it as input on other measure, such as ([utilization%] = ([ActualDaysWorked] / [NoofWorkingDays]).
Note that, I can do analysis with the given MDX, but I need to deploy it with precalculated values in cube, so that end user can directly use the cube.
Kindly let me know, if more details required, Thank you.
Welcome to SSAS and MDX. Now to the answer.
I need to add this named column on Fact table as measurement. I am
having trouble with the below items:
Creating named query with MDX expression mentioned. Adding a [Number
of Working Days] as measure in Fact table.
You dont need to add it to the Fact table at all. Open your SSAS project, in your object explorer double click your cube. Now on the top left hand you will see a CALCULATIONS tab. In the CALCULATION tab, Click new calculated member, the icon has a calculator on it.
Please correct me, If I am doing it in wrong way. My requirement is I
need a [NoOfWorkingDays] as measure in fact table, so that I can use
SSAS aggregate to use it as input on other measure, such as
([utilization%] = ([ActualDaysWorked] / [NoofWorkingDays]).
If I remember correctly, the calculated members will not be added into the Aggregations, however the underlying measures would be. Secondly if you are wondering that you can use your calculated Measure in another calculated measure. The answer is yes you can use it in another calculated measure. So this is totally possible
> ([utilization%] = ([ActualDaysWorked] / [NoofWorkingDays])
where [utilization%] and [NoofWorkingDays] are calculated measures.
We have a SSAS 2012 tabular model at our disposal which we are reporting on with Tableau.
Currently, we have a dimension [Material] with an attribute [Department].
What we're trying to do is create an MDX calculated member equivalent in DAX for implementing a custom grouping of the [Department] attribute.
For instance:
CREATE MEMBER [Material].[Department].[AB] AS
AGGREGATE({[Material].[Department].&[A], [Material].[Department].&[B]})
We tried to add a calculated member [AB] in hierarchy [Material].[Department] in Tableau with this MDX expression:
AGGREGATE({[Material].[Department].&[A], [Material].[Department].&[B]})
At design time, the expression validates but when we try using that member in our report we get an error stating that this kind of MDX calculated members are not supported in DAX.
Does anyone know of an equivalent or if and how we should get this MDX member to work?
Use SUMX.
I would imagine your DAX measure would look similar to:
=SUMX(FILTER('Material', 'Material'[Department]=OR("A","B")),[MaterialQuantity])
A Tabular model does not support the creation of calculated members in the model. The best you can do is to use a query-scoped calculated member by defining it in the MDX query.
E.g.
WITH MEMBER [Material].[Department].[All].[AB] AS
AGGREGATE({[Material].[Department].&[A], [Material].Department].&[B]})
SELECT ...
FROM ...
I have a dimension list of Product Codes and a measure called ACV in my cube. I need to be able to calculate the maximum ACV value for each product code.
I have got as far as the calculation below but that returns the sum of ACV for all products.
MAX([Products].[Product Code].[Product Code].Members, [Measures].[ACV])
I'd be grateful for input on how to resolve my problem.
Thanks!
If you want the maximum evaluated semiadditively by the grain of your model designed in the data source view, you should add a new measure (based on the same source field as the ACV measure) to your cube add set its AggregationFunction property to Max. More on aggregation functions in SSAS.
