MDX Start and End Time per transaction

Question

I hope you can help i have tried so many way to try get this right with no luck. I am trying to get out the player account number the date and start and end date time and maybe calculate the play duration between the start and end times.

I would like the output to look something like this.

PlayerAccount | GamingDate | StartTime | EndTime | PlayDuration | ActualWin

I always seem to return the start and end time for the whole day and not Per account.

 WITH 
  SET [MySet] AS 
      [Customer].[Player Account Number].Children*
      Head
      (
        NonEmpty
        (
          [Start Time].[Hour].Children
         ,[Measures].[Actual Win]
        )
       ,1
      )*
      Tail
      (
        NonEmpty
        (
          [End Time].[Hour].Children
         ,[Measures].[Actual Win]
        )
       ,1
      ) 
SELECT 
  {[Measures].[Actual Win]} ON 0
 ,{[MySet]} ON 1
FROM 
(
  SELECT 
      [Customer].[Player Account Number].&[1040002184]
    : 
      [Customer].[Player Account Number].&[1040002198] ON 0
  FROM Ratings
)
WHERE 
  {[Gaming Date].[Full Date].&[20150101]};

Usually first date and last date would be measures. If you only want results for those two player then use the WHERE clause rather than a sub-select:

WITH 
  MEMBER [Measures].[fDate] AS 
    Head
    (
      NonEmpty
      (
        [Start Time].[Hour].MEMBERS
       ,[Measures].[Actual Win]
      )
    ).Item(0).Item(0).Member_Caption 
  MEMBER [Measures].[lDate] AS 
    Tail
    (
      NonEmpty
      (
        [End Time].[Hour].MEMBERS
       ,[Measures].[Actual Win]
      )
    ).Item(0).Item(0).Member_Caption 
SELECT 
  {
    [Measures].[fDate]
   ,[Measures].[lDate]
   ,[Measures].[Actual Win]
  } ON 0
 ,{[Customer].[Player Account Number].Children} ON 1
FROM Ratings
WHERE 
  ([Gaming Date].[Full Date].&[20150101],
   { [Customer].[Player Account Number].&[1040002184]
    ,[Customer].[Player Account Number].&[1040002198]});

This is a working AdvWrks script which does the sort of thing you're trying to achieve:

WITH 
  MEMBER [Measures].[firstDate] AS 
    Head
    (
      NonEmpty
      (
        [Date].[Date].[Date].MEMBERS
       ,[Measures].[Internet Sales Amount]
      )
    ).Item(0).Item(0).Member_Caption 
  MEMBER [Measures].[lastDate] AS 
    Tail
    (
      NonEmpty
      (
        [Date].[Date].[Date].MEMBERS
       ,[Measures].[Internet Sales Amount]
      )
    ).Item(0).Item(0).Member_Caption 
SELECT 
  {
    [Measures].[Internet Sales Amount]
   ,[Measures].[firstDate]
   ,[Measures].[lastDate]
  } ON 0
 ,NON EMPTY {[Promotion].[Promotion].MEMBERS} ON 1
FROM [Adventure Works];

If you'd rather pull back a member instead of using Measures I think the GENERATE function will work like this AdvWrks example:

WITH 
  SET [aSet] AS 
    Generate
    (
      [Promotion].[Promotion].MEMBERS
     ,
        [Promotion].[Promotion].CurrentMember
      * 
        Head
        (
          NonEmpty
          (
            [Date].[Date].[Date].MEMBERS
           ,[Measures].[Internet Sales Amount]
          )
        )
    ) 
SELECT 
  {[Measures].[Internet Sales Amount]} ON 0
 ,NON EMPTY 
    {[aSet]} ON 1
FROM [Adventure Works];
