MDX question: how to find last set value "valid from"

Hi, i try to implement this situation:

I have a parameter, defined on year level.

2008: 15%
2010: 17%
2015: 19%

For the years between the years, where a number was entered,
I want to display the values from the previous year:

I expect this:
2008 15%
2009 15%
2010 17%
2011 17%
2012 17%
2013 17%
2014 17%
2015 19%
2016 19%

I have tried with ParallelPeriod. But it's correct?

Thanks Alot for the answer,
Giovanni

no one have a solution?

i try this, but i think isn't correct...

CREATE MEMBER CURRENTCUBE.[MEASURES].[ValidFrom] AS ([Measures].[Actual
Sales Qty]) ;

SCOPE
([Month].[Month].&[24]:[Month].[Month].&[27],[MEASURES].[ValidFrom]);
THIS =

ParallelPeriod
(
[Month].[Month].[Month],
1,
[Month].[Month].&[25]
) ;
END SCOPE;

SCOPE
([Month].[Month].&[28]:[Month].[Month].&[35],[MEASURES].[ValidFrom]);
THIS =

ParallelPeriod
(
[Month].[Month].[Month],
1,
[Month].[Month].&[26]
) ;
END SCOPE;
