Universe Built on a MultiProvider

Hi,

We built a Universe based on a BEX Query that is developed against a MultiProvider.

Our MultiProvider have 3 cubes. 1 Each for Year 2008, 2009 & 2010.

Now in the Univeser we have Dimension INFOPROVIDER.

When we built a WEBI report, we are adding this INFOPROVIDER to the Filter Conditions section of WEBI report and setting it to Cube that holds 2010 data.

But when we execute the WEBI, we noticed the SQL in SM51 transaction code is querying data in all 3 cubes .

Any thoughts why is the WEBI is accessing all 3 cubes instead of Just 1 even though we restricted the WEBI on INFOPROVIDER value?.

Thanks in advance.
