Hello everyone,
I am a mdx newbie and I neep (please) your Help. I have created a Cube that has 3 dimensions. Products, Time and Warehouses. The Time Dimension is :
Time --> Year , Quarter, Month, Week, Day
The Measure tha I need for my Calculation is [Store Demand]
I have searched to find the formula for the Moving Average for each one Month and I found this :
//
/*Returns the average value of a member over a specified time interval.*/
CREATE MEMBER CURRENTCUBE.[MEASURES].[Moving Average]
AS Avg
(
[<<Target Dimension>>].[<<Target Hierarchy>>].CurrentMember.Lag(<<Periods to Lag>>) :
[<<Target Dimension>>].[<<Target Hierarchy>>].CurrentMember,
[Measures].[<<Target Measure>>]
)
// This calculation returns the average value of a member over the specified time interval.
)'
So I wrote my MDX -->
'Avg(
[Time].[Month].CurrentMember.Lag(1):[Time].[Month],
[Measures].[Period Demand]'
But I get the error...#VALUE! The CURRENTMEMBER function expects a hierarchy expression for the 0 argument...
Sorry, I really dont understand it...:crying:
Thank you really for any Help!!:-):-):-)

Try
Avg(
{[Time].[Month].CurrentMember.Lag(1):[Time].[Month].CurrentMember},
[Measures].[Period Demand])

The same error using this. I really dont understand. 🙁 :doze:-->
'Avg(
{[Time].[Month].CurrentMember.Lag(1):[Time].[Month].CurrentMember},
[Measures].[Period Demand])'

The syntax I provided is correct (have checked :-P)
What MDX query are you running to get the error?

Thank you again. I dont know if I am wrong but I use it on the cube. I create the Calculate Member with this syntax...

What is the syntax of the query you are running (not the calculated member)? If you are using Excel you need to run a trace on the server to get the MDX query
The syntax looks correct so it will be a contextual problem eg you are using a different date than the one specified

Hello again...
I have a different problem now... I could not calculate the moving avarage with an MDX Query so I tried it with sql. It works but I realy know that the correct way would be an mdx query...
Anyway, so I have the moving Avarage on the Day basis but I want to have an avg in every Time level... So I tried this code -->
'iif ([Time].currentmember.level.Name="(All)",
Avg({DESCENDANTS([Time].CURRENTMEMBER,4)},[Measures].[MovingAvarage]),
iif ([Time].currentmember.level.Name="Year",
Avg({DESCENDANTS([Time].CURRENTMEMBER,3)},[Measures].[MovingAvarage]),
iif ([Time].currentmember.level.Name="Quarter",
Avg({DESCENDANTS([Time].CURRENTMEMBER,2)},[Measures].[MovingAvarage]),
iif ([Time].currentmember.level.Name="Month",
Avg({DESCENDANTS([Time].CURRENTMEMBER,1)},[Measures].[MovingAvarage]),
iif ([Time].currentmember.level.Name="Day",
[Measures].[MovingAvarage],NULL)))))'
But it seems tha it Sums the Data In each Time level...
I get the MovingAvarage from my View and his Aggregate property is to sum...
I think there is the problem... I use SQL Server Standard Edition and I cant select for the Aggregate property the none property.
I run my MDX on the cube and I check the results on the Cube Browser. The MDX is so different from SQL and I really cant run anything on the SQL Server Analysis Query Analysizer.....
What am I doing wrong? Is there any other way? I really dont know and I need really your Help... Please Help me!!!!!

Hello everyone!
I did that :
I created two new Measures:
Measure : CountFinalStockDays with AggregateFunction : Count
Measure : SumFinalStockDays with AggregateFunction : Sum
New Calculate Measure : [FinalStockDays] --> MDX :
'[Measures].[SumFinalStockDays]/[Measures].[CountFinalStockDays]'
And it works now. Thank you all for you help! And if there is a better way to do this please tell me!!:-):-):-):-)
