Where Clause using another Dimension Value - ssas

Question

I'm trying to create a Calculated Member in my cube with where clause but couldn't figure how to achieve the proper result.
I created a calculated member "Outlook" using the below code to display only Forecast values.
CREATE MEMBER CURRENTCUBE.[Measures].[Outlook]
AS SUM(([Source Profile].[Source Profile Hierarchy].CurrentMember,
[Source Profile].[Profile Level01].&[Outlook]),
[Measures].[USD Amount]),
FORMAT_STRING = "#,##0;(#,##0)",
VISIBLE = 1 , DISPLAY_FOLDER = 'USD' , ASSOCIATED_MEASURE_GROUP = 'CARS';
Cube Result
Now I would like to filter the results dynamically based on another hidden dimension "Current_Month". This dimension always has current financial period value and it's corresponding outlook profile
Year_Month Outlook_Profile
2015010 10 + 2
Expected result should be "Outlook" measure showing value based on Current_Month dimension, which is '10 + 2' and rest of them should be 0
Expected result
Just to explain the requirement in SQL terms, I would like to achieve the below in MDX
Where Fact.Source_Profile=Dimension.Source_Profile
instead of
Where Fact.Source_Profile='10 + 2'
I'm not sure how to achieve this in Where Clause or by another means. I could see examples of hard coding values, like year.&[2015] but haven't seen one using dynamic values.

I found a solution myself and thought of sharing the same. Used StrToMember function to pass hidden dimension's member as a variable here.
CREATE MEMBER CURRENTCUBE.[Measures].[Outlook]
AS (
Sum
(
(
[Source Profile].[Source Profile Hierarchy].CurrentMember,
strtomember("[Source Profile].[Source Name].&[" + [Outlook Profile].[Outlook Profile].&[1].Member_Caption + "]")
)
,[Measures].[USD Amount]
)
),
FORMAT_STRING = "#,##0;(#,##0)",
VISIBLE = 1 , DISPLAY_FOLDER = 'USD' , ASSOCIATED_MEASURE_GROUP = 'CARS' ;
