MTD Function not working with SCOPE - ssas

Question

SCOPE ([Measures].[Net IMS Volume]);
( [Time].[Time Calculations].[MTD] )
= SUM(
MTD([Time].[Time Hierarchy 1].CURRENTMEMBER)
,[Time].[Time Calculations].[Current Time]
);
END SCOPE;
I was expecting my MTD to be displayed across the dates of the month. but the result is that I just get data at the Month Level.
When I do the same thing over at SSMS w/ the ff.:
WITH MEMBER [Time].[Time Calculations].MIKE2 AS
SUM
(
MTD([Time].[Time Hierarchy 1].CURRENTMEMBER)
,[Time].[Time Calculations].[Current Time]
)
SELECT
{
([Time].[Time Calculations].[MTD],[Measures].[Net IMS Volume])
,([Time].[Time Calculations].MIKE2,[Measures].[Net IMS Volume])
} ON 0
,[Time].[Time Hierarchy 1].[Date] ON 1
FROM [My Cube];
I get data at Date Level. I'm experiencing this on YTD function also.

Your time dimensions may not be typed correctly. Specific typing is required for the YTD and MTD to function as expected.
MSDN reference to YTD function: https://msdn.microsoft.com/en-us/library/ms146039.aspx
In the "remarks" section of the definition:
If a member expression is not specified, the default is the current
member of the first hierarchy with a level of type Years in the first
dimension of type Time in the measure group.
The Ytd function is a shortcut function for the PeriodsToDate function where the Type
property of the attribute hierarchy on which the level is based is set
to Years. That is, Ytd(Member_Expression) is equivalent to
PeriodsToDate(Year_Level_Expression,Member_Expression). Note that this
function will not work when the Type property is set to FiscalYears.
You could test if this is your problem by converting to the use of PeriodsToDate:
WITH MEMBER [Time].[Time Calculations].MIKE2 AS
SUM
(
PeriodsToDate(
[Time].[Time Hierarchy 1].[Month Level]
, [Time].[Time Hierarchy 1].CURRENTMEMBER
)
,[Time].[Time Calculations].[Current Time]
)
SELECT
{
([Time].[Time Calculations].[MTD],[Measures].[Net IMS Volume])
,([Time].[Time Calculations].MIKE2,[Measures].[Net IMS Volume])
} ON 0
,[Time].[Time Hierarchy 1].[Date] ON 1
FROM [My Cube];
