With MDX how to sort by month - mdx

Question

How do I sort by month. Now the sorting is alfabetical. And that is not correct. I want january before april - not the other way run :)
Im working in report builder 3.0 and have tried this (=format(Fields!Måned.Value,"MM") as a calculated member called monthsort, but it dosent Work. (Måned = month in Danish).
I have the following MDX-code:
WITH
SET [prodSet] AS
[Borger].[Anonym Borgernøgle DPR].[Anonym Borgernøgle DPR].ALLMEMBERS
SET [prodDtSet] AS
NonEmpty
(
[prodSet]
*
{
( [SundhedOgOmsorg - Ydelse].[Ydelse].[Ydelse].ALLMEMBERS *
[Kalender].[År].[År].ALLMEMBERS *
[Kalender].[Måned].[Måned].ALLMEMBERS )
}
,[Measures].[Antal unikke brugere - Visiteret Tid]
)
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].[Antal unikke brugere - Visiteret Tid] } ON 0
,[prodDtSetFiltered] ON 1
FROM
(
SELECT
{
[SundhedOgOmsorg - Ydelse].[Ydelse].&[12.1 Hjemmetrænerforløb]
,[SundhedOgOmsorg - Ydelse].[Ydelse].&[12.2 Komb. Hjemmetræner & Terapeutforløb]
,[SundhedOgOmsorg - Ydelse].[Ydelse].&[12.3 Komplekse Rehabiliteringsforløb]
,[SundhedOgOmsorg - Ydelse].[Ydelse].&[12.7. hverdagsrehab. revis.gr. m. tp.]
} ON COLUMNS
FROM
(
SELECT
{[SundhedOgOmsorg - Modul].[Modul].&[Hjemmehjælp]} ON COLUMNS
FROM [FrbLis]
)
)
WHERE
[SundhedOgOmsorg - Modul].[Modul].&[Hjemmehjælp]

Answer 1

You can try and pull the
MEMBER [Measures].[MånedSortKey] AS [Kalender].[Måned].CURRENTMEMBER.PROPERTIES('KEY')
You can also use MEMBER_KEY instead of PROPERTIES('KEY')
And Sort by it in the report.
(I'm assuming your Key is a Date or a Int which should be more sortable than a string)
(...)
MEMBER [Measures].[MånedSortKey] AS [Kalender].[Måned].CURRENTMEMBER.PROPERTIES('KEY')
SELECT
{
[Measures].[Antal unikke brugere - Visiteret Tid],
[Measures].[MånedSortKey]
} ON 0,
[prodDtSetFiltered] ON 1
FROM (
(...)

You will probably need to use the following function in your script:
Order : https://msdn.microsoft.com/en-us/library/ms145587.aspx
The <numeric expression> to use as an argument will be the Month member's .membervalue property.
Taking mxix measure (I've used membervalue rather than key - although both should work) you should be able to enforce an order inside the mdx:
WITH
MEMBER [Measures].[MånedSortKey] AS
[Kalender].[Måned].CURRENTMEMBER.membervalue
SET [prodSet] AS
[Borger].[Anonym Borgernøgle DPR].[Anonym Borgernøgle DPR].ALLMEMBERS
SET [prodDtSet] AS
NonEmpty
(
[prodSet]
*
{
( [SundhedOgOmsorg - Ydelse].[Ydelse].[Ydelse].ALLMEMBERS *
[Kalender].[År].[År].ALLMEMBERS *
[Kalender].[Måned].[Måned].ALLMEMBERS )
}
,[Measures].[Antal unikke brugere - Visiteret Tid]
)
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].[Antal unikke brugere - Visiteret Tid] } ON 0
,ORDER(
[prodDtSetFiltered],
[Measures].[MånedSortKey],
BDESC
) ON 1
FROM
