The MDX function CURRENTMEMBER failed because the coordinate for the 'Date' attribute contains a set - ssas

Question

I'm trying to run this query:
select [Dim Date].[Date] on ROWS,
{[Measures].[Available Time Net],[Measures].[Logged On Time Net]} on columns
from [OTS Agent Time Net Data]
where {[Dim Date].[Date].&[08/01/2014]:[Dim Date].[Date].&[12/31/2014]}
I want to get the measures that exist in the where clause, but I also want to show the dates on the rows. I keep getting an error.

Answer 1

Why not just add the set directly to the ROWS ?
SELECT
NON EMPTY
{
[Dim Date].[Date].&[08/01/2014] : [Dim Date].[Date].&[12/31/2014]
} ON ROWS
,{
[Measures].[Available Time Net]
,[Measures].[Logged On Time Net]
} ON COLUMNS
FROM [OTS Agent Time Net Data];

Answer 2

You cannot use the same hierarchy ([Dim Date].[Date]) both on one axis and in the slicer (MDX tutorial); I guess using a sub-query would be fine for your example:
select
[Dim Date].[Date] on ROWS,
{[Measures].[Available Time Net],[Measures].[Logged On Time Net]} on columns
from (
select {[Dim Date].[Date].&[08/01/2014]:[Dim Date].[Date].&[12/31/2014]} on 0
from [OTS Agent Time Net Data]
)
Hope that helps.
(edit: using a named-set or using the slicer content right in the axis - see other responses - is a bit different because the request is filtering on a range of days but select [Dim Date].[Date] does not necessarily displays days; that could for example be the 'All' of the hierarchy of [Dim Date].[Date])

Answer 3

I agree with Marc's answer and that's probably the best way to do it. But there is one more way to do it, which doesn't need subselect, by making use of named sets.
with set DateRange AS
{[Dim Date].[Date].&[08/01/2014]:[Dim Date].[Date].&[12/31/2014]}
select NON EMPTY DateRange on ROWS,
{[Measures].[Available Time Net],[Measures].[Logged On Time Net]} on COLUMNS
from [OTS Agent Time Net Data]
EDIT
As per your request, if you want to additionally filter by time, here's one way to proceed. Replace the defenition of set DateRange with the below:
with set DateRange AS
EXISTS({[Dim Date].[Date].&[08/01/2014]:[Dim Date].[Date].&[12/31/2014]}
,[Dim Time].[Time].&[1930]
, "Time Net"
)
Few things which you need to fill in here..
Assuming time dimension's hierarchy to be [Dim Time].[Time]. Please replace with the actual name along with the member's format(Assumed it to be &[1930]
Also, Time Net is the measure group name to which the measures [Measures].[Available Time Net] and [Measures].[Logged On Time Net] belong to. Again, replace with original name.
