Problem in creating reports using BI fields

Hi,

I have created a cube using 3 Dimensions and 1 measure. One of the dimensions is a time dimension. I have also used the ADD BI command to get the Year to Date and Year over year % . This works perfectly with the cube. But when I try and create a report I am unable to display the figures for the above mentioned columns. I get Null data there.

Does anybody have any suggestions as to why this is happening and what the way to overcome this.

Thanks in advance

Could you provide more information on how you are creating the report and which columns are returning nulls?
