Day and Month date format - Calculating a measure only for the last day date format

Question

Good evening all,
I'm really struggling with a MDX query and so would greatly appreciate your help ..
Here is a simplified representation of my data:
Id
Tenor
VarX
1
10-Jan-14
10
2
10-Jan-14
10
3
10-Jan-14
10
4
11-Jan-14
10
5
12-Jan-14
10
6
13-Jan-14
10
7
Feb-14
10
8
Mar-14
10
9
Apr-14
10
And here is the MDX result I’m trying to get:
Tenor
VarX
VarY
10-Jan-14
30
0
11-Jan-14
10
0
12-Jan-14
10
0
13-Jan-14
10
90
Feb-14
10
0
Mar-14
10
0
Apr-14
10
0
Where: if tenor is the last tenor in day format (i.e. dd-mmm-yy) VarY = total sum of VarX else VarY = 0
Here is a first try below which hopefully will help you understand my problem.
MEMBER [Measures].[VarY] AS
IIF (
ISEMPTY([Measures].[VarX])
OR vbamdx!Len([Tenor].CURRENTMEMBER.Name) <= 6 
OR TAIL(
FILTER(
{[Tenor].[ALL].CHILDREN},
NOT (ISEMPTY([Measures].[VarX])) AND vbamdx!Len([Tenor].CURRENTMEMBER.Name) > 6 
).ITEM(0).Name <> [Tenor].CURRENTMEMBER.Name,
NULL,
SUM ( [Tenor Group].[Tenor Group].[all], [Measures].[Delta] ) )
Please let me know if you have any ideas and/or advice.
Thanks in advance! Kevin

Hey Aleksandr
Tenor is a string. The tenor table is used by other reports too and contains tenors in day, month, etc format (e.g. 01-Jan-14, 02-Jan-14, 03-Jan-14, ..., Jan-14, Feb-14, ...).
This is why I was trying to differentiate the 2 "groups" of tenor using length.
Something like:
MEMBER [MEASURES].[MOUT] AS 
iif(
isempty([Measures].[VarX]),
null,
iif(
(Len([Tenor].CURRENTMEMBER.NEXTMEMBER.Name) =  
 Len([Tenor].CURRENTMEMBER.Name)
null,
SUM ( [Tenor].[all], [Measures].[VarX])))
