Problem in displaying columns in a Dimensional model

[backhandx]

Hi averyone,

I'm new in dimensional reporting and i have a serious problem.
I created a simple report in Report Studio and I have a strange behavior.
Actually, I have 2 members A and B from two different hierarchies in the same dimension. When I drag the 2 members in the column of a crosstab, only column A is displayed even if the B column is not null ( I managed to run the report with only the column B and I is dispalyed in the crosstab with a non null value).
Is this happening because the members are from different hierarchy?
Can anyone help me out please!

Thanks in advance
