Calculating Avg Orders per day using MDX - ssas

Question

I am trying to create a calculated member which should returns the averages orders per week per person.
Below is the screen shot where the client will be looking to forecast the work load. Staff may not work all the days in a week.
The calculation will be : No of Orders / No of scheduled days in that week.
It would not be very hard to calculate this if the week name is in the same hierarchy of the date, but in this case it is not in hierarchy but just member of the dimension.
This is the MDX I've tried:
Avg ( Descendants
( [Date Planned].[Date Planned].CurrentMember, [Date Planned].[Date Planned].[Date Planned] ),
[Measures].[Orders Qty] )

Answer 1

It would be much easier when you have week and day added into the hierarchy, but if you don't have possibility to have this added, there is different non elegant solution.
If you would assume that this member will always be used with Week on rows your member calculation would be as follow:
This will work correctly only with weeks on rows - so I would recommend to extend your Calendar hierarchy by week and day and then we can have a chat about much more elegant solution.

Answer 2

Try using this:
WITH MEMBER [Measures].[avg_week] AS
Avg ( EXISTING { [Date Planned].[Week Of Year].[Week Of Year] },
[Measures].[Orders Qty] )
SELECT [Measures].[avg_week] ON COLUMNS,
NON EMPTY
{ [Person].[PersonName].[PersonName] * [Date Planned].[Week Of Year].[Week Of Year] } ON ROWS
FROM [Your cube]
Let me know if this can help you.

Answer 3

Maybe something like the following:
WITH
MEMBER [Measures].[PlannedDayCnt] AS
Count
(
Exists
(
(EXISTING
[Date Planned].[Date Planned].[Date Planned].MEMBERS)
,[Date Planned].[Week Of Year].currentmember
)
)
MEMBER [Measures].[Averge Orders] AS
[Measures].[Orders Qty] / [Measures].[PlannedDayCnt]
SELECT
{
[Measures].[Orders Qty]
,[Measures].[PlannedDayCnt]
,[Measures].[Averge Orders]
} ON 0
,
[Person].[PersonName].[PersonName]
* [Date Planned].[Week Of Year].[Week Of Year] ON 1
FROM [aCube];
I'd like to test but unsure how to model your scenario in the AdvWrks cube.

Answer 4

I would first want to see how many "dates" belong to the week. That would be easy as it would be those days when Orders were placed for that person that week.
NonEmpty
(
[Date Planned].[Date Planned].[Date Planned].MEMBERS,
(
[Date Planned].[Week Of Year].currentmember,
[Person].[PersonName].currentmember,
[Measures].[Orders Qty]
)
)
Now that you have the requisite dates for the "current" week and the "current" person, you would need to calculate the average order quantity for these set of dates. It would look like this:
AVG
(
NonEmpty
(
[Date Planned].[Date Planned].[Date Planned].MEMBERS,
(
[Date Planned].[Week Of Year].currentmember,
[Person].[PersonName].currentmember,
[Measures].[Orders Qty]
)
)
, [Measures].[Orders Qty]
)
Your final construct would need to be:
WITH MEMBER Measures.AverageOrderPerDay AS
AVG
(
NonEmpty
(
[Date Planned].[Date Planned].[Date Planned].MEMBERS,
(
[Date Planned].[Week Of Year].currentmember,
[Person].[PersonName].currentmember,
[Measures].[Orders Qty]
)
)
, [Measures].[Orders Qty]
)
SELECT
{
[Measures].AverageOrderPerDay,
[Measures].[Orders Qty]
}
ON 0,
[Person].[PersonName].[PersonName].MEMBERS
* [Date Planned].[Week Of Year].[Week Of Year].MEMBERS ON 1
FROM [YourCube]
