How to build MDX query for two periods of time?

Question

I have the following MDX:
SELECT NON EMPTY
[Measures].[Returns],
[Measures].[Returns]
ON COLUMNS,
NON EMPTY
([Employees].[Company].[Company].ALLMEMBERS )
DIMENSION PROPERTIES MEMBER_CAPTION, MEMBER_UNIQUE_NAME ON ROWS
FROM
SELECT
STRTOSET("[Exec Date].[Hierarchy].[Month Num].&[2014]&[1]", CONSTRAINED)
) ON COLUMNS FROM [cbSales]
WHERE
IIF(
STRTOSET("[Exec Date].[Hierarchy].[Month Num].&[2014]&[1]", CONSTRAINED).Count = 1,
STRTOSET("[Exec Date].[Hierarchy].[Month Num].&[2014]&[1]", CONSTRAINED),
[Exec Date].[Hierarchy].currentmember
Both columns shows returned data for month 2014/01
I want to have data for the next month (2014/02) in the second column.
How can I change the query to achieve my goal.

Hi,
To achieve this you need to create another measure with the help of ParallelPeriod function. Check the following example;
WITH MEMBER [Measures].[Sales Amount Current] AS [Measures].[Sales Amount]
MEMBER [Measures].[Sales Amount Next] AS ([Measures].[Sales Amount], PARALLELPERIOD([Date].[Calendar].[Month],-1, [Date].[Calendar].CURRENTMEMBER)), format_string = "Currency"
MEMBER [Measures].[Current Month] AS [Date].[Calendar].CURRENTMEMBER.Member_Caption
MEMBER [Measures].[Next Month] AS PARALLELPERIOD([Date].[Calendar].[Month],-1, [Date].[Calendar].CURRENTMEMBER).Member_Caption
SELECT {[Measures].[Current Month], [Measures].[Sales Amount Current], [Measures].[Next Month], [Measures].[Sales Amount Next]} ON COLUMNS,
{[Product].[Category].[Category].MEMBERS} ON ROWS
FROM [Adventure Works]
WHERE [Date].[Calendar].[Month].&[2007]&[10]
For ParallelPeriod specify -1 for "Numeric Expression" to navigate forward of the date hierarchy.
