Accumulated and interannual ssas mdx

Question

Hello!
I'm (more than) new in the issue of SSAS and MDX and I have seen several examples for calculating accumulated sounding Chinese to me. In these examples illustrate that the function that could / should be used is PeriodsToDate or Ydt,  but I can not display
anything (no errors, but the result is NULL). I created several tests calculated members for use in SSRS and excel. These are three of the many tests that have been made ​​without success:
CREATE MEMBER CURRENTCUBE.[Measures].prueba_acum
AS sum([Measures].[IMPORTE GASTO],YTD([Dim Tiempo].[Año])),
FORMAT_STRING = "Standard",
VISIBLE = 1 ;
CREATE MEMBER CURRENTCUBE.[Measures].prueba_acum_2
AS sum([Measures].[IMPORTE GASTO],
PeriodsToDate(
[Dim Tiempo].[Año],
[Dim Tiempo].[Mes].currentmember
VISIBLE = 1 ;
CREATE MEMBER CURRENTCUBE.[Measures].prueba_acum_4
AS SUM([Measures].[IMPORTE GASTO],YTD([TBP5 Dim Tiempo].[Mes].CurrentMember)),
VISIBLE = 1 ;
What I need to get with the calculated members are:
- Accumulated current year: For MARCH month, the total amount from January to March for the selected year.
- Accumulated last year: For MARCH month, the total total amount from January to March before the selected year.
- Interannual: For MARCH month, the total amount from the previous MARCH to FEBRUARY of the selected year.
Any clue will be helpful!
Thank you!

Hello trinity9,
As there is no date ” Calender  Month of year” configured in the adventure works I will illustrate using “week of year”  In the example below , you will find a the accumulative amount till a chosen week for each year.
Accumulated current year:
WITH
MEMBER [Measures].[Year to Date Reseller Sales] AS
Aggregate
PeriodsToDate
[Date].[calendar Weeks].[calendar Year]
,Exists
Exists
[Date].[calendar Weeks].[calendar Week]
,[Date].[calendar Week of Year].&[27]
,[Date].[calendar].CurrentMember
).Item(0)
,[Measures].[Reseller Sales Amount]
SELECT
[Measures].[Reseller Sales Amount]
,[Measures].[Year to Date Reseller Sales]
} ON COLUMNS
,{[Date].[calendar Year].[calendar Year].MEMBERS} ON ROWS
FROM [Adventure Works];
Accumulated last year:  take  [Date].[calendar].CurrentMember.PrevMember
 instead
Interannual: You have to sum two PeriodsToDate calculations
