I found this little code where it dynamically calculates TOTALs for all Dimension/Hierarchy I want.
This is close to what I need but will not work for Dimensions that have different number of Hierarchy Levels (Attribute Hierarchy). Current Code only works if there is only one Attribute Hierarchy because of CurrentMember.Parent. I could use CurrentMember.Parent.Parent for Dimension.Hierarchy that have two levels and so on but would not work for the the ones with only one Attribute Hierarchy (Level).
CALCULATE;
CREATE MEMBER CURRENTCUBE.[Measures].[Total On Hand Amount]
AS ([Measures].[On Hand Amount],Axis(1).Item(0).Item(0).Dimension.CurrentMember.Parent),
FORMAT_STRING = "#,#",
VISIBLE = 1 ;
I would like to make this MDX code work for any Dimension.Hierarchy regardless of number of Attribute Hierarchy (Level/s).
Any help is appreciated!!
You can use the ancestors function instead of parent. It takes a dimension parameter and a second parameter which shows how many levels you want to get (how deep in the tree to go). So if you know how many levels your dimension has you can use something like:
Ancestors(Axis(1).Item(0).Item(0).Dimension.CurrentMember, 5)
Instead of a number you can also add a dimension level as a second parameter. Then it will go as deep as the dimension level specified - so if you add the root dimension level it should get to there
(Axis(1).Item(0).Item(0).Dimension.Levels(0).Item(0), [Measures].[On Hand Amount])
Above gave me the correct answer, total for a measure for dynamic selection of any dimension but this MDX calculation would not work from PowerBI(DAX) report, which is merely PowerBI's limitation.
I got the TOTAL working now with this -
SCOPE(DESCENDANTS([Warehouses].[Warehouses],,AFTER));
[Measures].[Total On Hand Amount] = (ROOT([Warehouses]),[Measures].[On Hand Amount]);
END SCOPE;
I just have to repeat this SCOPE for each [Dimension].[Hierarchy] in the cube to make the TOTAL work for any selection including multiple dimensions from Power BI. It does not have dynamic functionality like Axis() did, but it yields the result I needed.
Hope this would help someone else too!!

I have a simple Data Cube for computing shared expenditures with one measure Amount and some dimensions and hierarchies but interesting one would be Relationship. It describes who bought something for whom. It's structure is:
Who
For whom
Relationship key
I am trying to code a calculation representing debt. For example if I bought something for sharing usage it would be half of 0.5 * Amount. On the other hand, if I bought something for myself it would be 0 * Amount.
As far I tried following calculation:
IIF(
[dimRelationship].[Relationship].currentMember = [dimRelationship].[Relationship].[RelatonshipID].&[MeShared],
[Measures].[Amount]*0.5,
[Measures].[Amount]*0)
It works good only at lowest RelationshipID level. When I roll-up browsered pivot-table it is acting according to else-expression. That is not really surprising because hierarchy's currentMember is not MeShared anymore. Another bad thing that total aggregation work neither - it would be most important as a general summary. Is there any suffix like .LeafMember or something like that which could help me perform this calculation?
Thank you in advance!
Best regards,
Max!
In you fact table add another column, in this column store the "Amount" multiplied by the relationshipID for that particular row. This will address you issue right out the box
Try SCOPE statement.
Firstly, create new calculation [Debt Calculation] as [Measures].[Amount]*0 /* as ELSE-scenario */
Then create a SCOPE:
SCOPE([Debt Calculation],[dimRelationship].[Relationship].[RelatonshipID].&[MeShared]);
THIS=[Measures].[Amount]*0.5;
END SCOPE;
If it's the lowest level of hierarchy and is a dimension key (which is used as a link to measure groups), it will re-calc higher levels of this dimension automatically. Please post a result here if not.
I have a requirement where report should show measures as "not applicable" if one selects a attribute which is not linked to that measure Group.
1) unrelateddimesnion= 'false' is not solving my problem because i have few default members.
2) I could able to show measure value as "not applicable " by Writing this MDX statement
([Customer].[customer name].[customer name], [measures].[sales forecast]) = 'not applicable'
but with this i have to repeat the same line for each and every attribute present in the dimension ( and also for each and every measure present in the measure Group)
can someone help me Writing the MDX for entire dimension instead for individual attribute. Thanks in advance.
Kind Regards
Mah
Bad news! An MDX script on your cube can't reference such a sub-cube in a simple way. You may have seen the LEAVES(dimension) function for a scope statement but that won't work when one attribute in a dimension has the [All] level and another has a selection. (That is to say the function returns the leaves of the dimension's key attribute). What you can do is use nested scope statements with the outer one filtering down to the list of measures you want to affect. That will at least save you typing a formula num_attributes * num_measures times. The scope statement may even accept the MEASUREGROUPMEASURES function. (When I last used that it only returned visible measures but that's probably what you want anyway.)
It may be easier to link measure group and dimension and let your data sit on the UNKNOWN member. (Or an explicit dummy member.) Then filters against or slices to real customer hierarchy values will exclude your [Sales Forecast] rows and show it as null. That's not something I've done and it'll have ramifications for error processing and you'll have to allow users sight of the unknown or dummy member. So recommend you play with the idea before you rely on it.
I hope this helps some.
I am on an MDX adventure and I'm at a point where I need to ask some questions.
I have a very basic dimension named Car. The attributes which comprise Car are as follows-
-Manufacturer
-Make
-Color
-Year
My fact table contains a sales measure ([Measures].[Sales]). I would like to know , without explicitly defining a user hierarchy, how to sum the sales from
a specific group in this hierarchy
For example, I want to sum the sales of all red Trucks made in 2002. My attempt errors out-
sum([Cars].[Make].[Make].&[Truck]&[Red]&[2002], [Measures].[Sales])
How can I navigate the attribute hierarchy in this way? I will be browsing the cube in excel
Thanks
If you open an mdx query in SSMS and drag a member from one of your attribute hierarchies into the query pain you will see the full name.
You definitely cannot chain hierarchies like this ...].&[Truck]&[Red]&[2002]
Each full name will likely be similar to what MrHappyHead has detailed but usually the attribute name is repeated e.g. for Make:
[Cars].[Make].[Make].&[Truck]
MrHappyHead have wrapped it all in the Sum function but this is not required - just wrap the coordinates in braces and a tuple is then formed which will point to the required area of the cube:
(
[Cars].[Make].[Make].&[Truck],
[Cars].[Color].[Color].&[Red],
[Cars].[Year].[Year].&[2002],
[Measures].[sales]
)
note: square brackets are pretty standard in mdx.
Is it something like:
Sum(
Cars.make.&[truck],
Cars.color.&[red],
Cars.year.[2002],
Measures.sales
)
i have the following script in my cube:
/*
The CALCULATE command controls the aggregation of leaf cells in the cube.
If the CALCULATE command is deleted or modified, the data within the cube is affected.
You should edit this command only if you manually specify how the cube is aggregated.
*/
CALCULATE;
CREATE MEMBER CURRENTCUBE.[Measures].[Scope TEST]
AS
STRTOVALUE(2),
VISIBLE = 1;
SCOPE([Locations].[LocationName].Members, [Measures].[Scope TEST]);
this = SUM([Locations].CURRENTMEMBER, STRTOVALUE(1));
END SCOPE;
what i would like for the script to do, is the following;
i have 5 locations, so when i add the measure scope test it should display 1 after each row. which is fine.
it, however, does not display 5 in the grand total row.
this is a simplified version of a script im trying to use. in that script i have yet to use a scope, but with a scope statement or without it, it doesn't really matter since there are no differences.
if anyone could point me in the right direction, any help would be much appreciated.
Are you seeing 1 in the grand total? If so, it may be that SUM(ALL, 1) = 1, as the ALL member does in a way count as a single member.
Try adding the All member's descendants into the count like this and let us know how it goes:
SCOPE([Locations].[LocationName].Members, [Measures].[Scope TEST]);
this = SUM(DESCENDANTS([Locations].CURRENTMEMBER, , AFTER), STRTOVALUE(1));
END SCOPE;
The Descendants function will return the set of descendants, so the All member will have all it's children (The members) evaluated for the set. So you'll get five members, summing that at one each should give you the number 5.
I have a particular dimension which has a multi level hierarchy because of the self join that i have in the dimension table.
In a particular level of hierarchy, I have values like Revenues and Expenses. I have a to frame a calculated member to get the Total Revenues and Expenses
I tried this and i am getting NULL while browsing the cube
AGGREGATE({[Account Hierarchy].[Account Hierarchy].Properties( "Account Name" )="Revenues"},[Measures].[Budget]))
Please let me know what i am missing here.
Probably you should be using a Member reference not accessing the Properties.
I would use the BIDS Cube / Calculations / Metadata pane to find that Member and drag it into the calculation to get the correct syntax.
