Format TM1 cube measures

[Rosanero4Ever]

Hi all,

I created a TM1 cube and I'm using it as datasource of a package of mine.
I formatted the measures in TM1 measure dimension and it is displayed well in cube viewer, TM1Web and other TM1 clients.
But in  Report Studio the format attribute is not applied.
The number  31.424212234 is displayed in TM1 as 31.42 because I formatted the number with two decimal digits but in Report Studio it is displayed as 31.424212234.
So the format attribute is not considered.
How can I set the format type in order to consider it in BI tools too?
Do I perform some actions when I create the FM model?
Thanks in advance
