the function LINREGSLOPE juste calculate the slope ( ie: a) of the equation Y= a *X+b

calculated member Name= Gain

LINREGSLOPE([TIME].[Month].&[2006-02-01T00:00:00]:[TIME].[Month].&[2006-06-01T00:00:00],[Mesures].[NumofCustomer],[TIME].[Month], [TIME].[Rank])

how can i do this please help

hi,

If I am not mistaken, I think you want to restrict the query based on static value instead of dynamic parameters. Right? If that is the case you can just include a where condition to your query like this:

where [Dimension].[Heirarchy].&[Member1]:[Dimension].[Heirarchy].&[Member2]

Note: Dimesion is your dimension name

Heirarchy is your heirachy name.

Member1 is the start date

Member 2 is the end date

I hope this will help.

Sincerely,

Amde

|||thanks amde,

no it's the opposite from static de dynamique.

if the user change the parametre the query will change too.i want to write my expresion with a parameter.

i want somethink like this:

linregslope([Time].[month].&"param1":[Time].[month].&"param2",[measures].[numberCustomer],[Time].[Month].[MonthNumber]).

if you have others questions feel free to ask me.

visite the link in my first post.

I hope this will help.

any idea is welcome

i found the solution

this isi the code:

WITH

set [RangeMonth] as LastPeriods(STRTOMEMBER (@.FromTIMEMonth,CONSTRAINED),STRTOMEMBER (@.ToTIMEMonth,CONSTRAINED))

MEMBER [Measures].[GAIN PER MONTH] AS 'LINREGSLOPE([RangeMonth],[Measures].[mymeasure],Rank([TIME].[Month], [TIME].[Month].Members))'

,format="percent"

SELECT NON EMPTY {[Measures].[GAIN PER MONTH],[Measures] ..........
