How to calculate the percentage?

In my cube, I've a date dimension and a time dimension. I would like to know how can I calculate the percentage of order count for a specific time?

I can get this.

Hour11/6/0611/7/069am601010am801011am6020

But how can I get this.

Hour11/6/0611/7/06

9am30%25%

10am40%25%

11am30%50%

I would like to use the calculation feature in available in the cube. How can I do this? Thanks!

Depends on whether the percentage is always based on the time hierarchy, regardless of which query axis it lies on, or is based on whichever hierarchy is on rows - Axis(1). In the former case, something like:

Member [Measures].[OrderFractionByTime] as

'[Measures].[Order Count]/

([Measures].[Order Count], [TimeOfDay].Parent)',

FORMAT_STRING = "Percent"

|||Hi Deepak,

Thanks for your reply but there are something that I don't understand. In your code, you use [TimeOfDay].Parent in the member calculation. However, in my own cube, the date dimension and time dimension are 2 separate dimensions. So, I don't expect my TimeOfDay.Parent will get the expected set.

The following is my Date and Time dimensions structure.
DimDate - The Date dimension is populated by extracting data from my OLTP.
Year
Month
DayOfMonth
Date
DayNameOfWeek

DimTime - The Time dimension is generated by cross join all the available hour, minute and second. (No. of records: 24 x 60 x 60)
Hour
Minute
Second

P.S. I'm quite new to BI and datawarehouse. If my Time hierarchy is not correct or using best practice, please let me know so that I can improve it.

Hi Alex,

Are you using AS 2000 or AS 2005 - if it's AS 2000, then something like:

Member [Measures].[OrderFractionByTime] as

'[Measures].[Order Count]/

([Measures].[Order Count], [DimTime].Parent)',

FORMAT_STRING = "Percent"

|||Hi Deepak,

I'm using AS 2005. The problem that I don't understand what [DimTime].Parent is pointing to. The Time dimension and Date dimension doesn't have any direct relationship in my cube. Is there any design fault?

Alex,

With AS 2005, the hierarchy should also be specified with [DimTime], so [DimTime].[TimeHierarchy].Parent points to the parent of the current [DimTime] member. For example, the parent of the hour "01" will be [DimTime].[TimeHierarchy].[All].
