With MDX hos to select first row? - mdx

Question

I am using sharepoint report builder.
In my data (se picture below) - I would like to get all the first row - the ones with yellow.
How do i do that.
Here is the MDX code. What should I write to get the yellow rows?
SELECT
NON EMPTY
{[Measures].[Antal unikke brugere - Visiteret Tid]} ON COLUMNS
,NON EMPTY
{
[Borger].[Anonym Borgernøgle DPR].[Anonym Borgernøgle DPR].ALLMEMBERS*
[SundhedOgOmsorg - Ydelse].[Ydelse].[Ydelse].ALLMEMBERS*
[Kalender].[År].[År].ALLMEMBERS*
[Kalender].[Måned].[Måned].ALLMEMBERS
}

You could try using one of the following iterative mdx functions:
Generate - https://msdn.microsoft.com/en-us/library/ms145526.aspx
Filter - https://msdn.microsoft.com/en-us/library/ms146037.aspx
To use filter is a little more convoluted as you need to specify specific tuples based on their relative positions. Generate is a little more straightforward. I will try to provide an example against the MS AdvWrks cube.
I think this is relatively similar to your situation:
SELECT
{[Measures].[Internet Sales Amount]} ON 0
,NON EMPTY
[Product].[Product Categories].[Product]
*
{
[Date].[Calendar].[Date].&[20050801]
:
[Date].[Calendar].[Date].&[20050807]
} ON 1
FROM [Adventure Works];
You would like the rows I've marked in red (there are lots of products with only 1 row)
So if we now apply the following multi-dimensional expression to the cube:
WITH
SET [prodSet] AS
[Product].[Product Categories].[Product]
SET [prodDtSet] AS
Generate
(
[prodSet] AS P
,Head
(
P.Current
*
NonEmpty
(
{
[Date].[Calendar].[Date].&[20050801]
:
[Date].[Calendar].[Date].&[20050807]
}
,(
P.Current
,[Measures].[Internet Sales Amount]
)
)
)
)
SELECT
{[Measures].[Internet Sales Amount]} ON 0
,[prodDtSet] ON 1
FROM [Adventure Works];
We get the results required:
Are you able to adapt my example to your context?
I will have a further play and supply a solution using Filter (it'll be, in a way, a little more complicated than the Generate approach)
Here is an approach using Filter:
WITH
SET [prodSet] AS
[Product].[Product Categories].[Product]
SET [prodDtSet] AS
NonEmpty
(
[prodSet]
*
{
[Date].[Calendar].[Date].&[20050801]
:
[Date].[Calendar].[Date].&[20050807]
}
,[Measures].[Internet Sales Amount]
)
SET [prodDtSetFiltered] AS
Filter
(
[prodDtSet]
,
(NOT
[prodDtSet].Item(
[prodDtSet].CurrentOrdinal - 1).Item(0)
IS
[prodDtSet].Item(
[prodDtSet].CurrentOrdinal - 2).Item(0))
OR
[prodDtSet].CurrentOrdinal = 1
)
SELECT
{[Measures].[Internet Sales Amount]} ON 0
,[prodDtSetFiltered] ON 1
FROM [Adventure Works];
Results are as following:
