Subject: expansion rate so high 

Hi,

   Is it normal when the expansion rate is about 1600% ?

   My  cube :     about one hundred million data;  

fact table has one lookup table;  

5 dimensions , in which 4 dimensions' encoding are fixed length,  separately
the length are 9, 8, 8, 33 ; 

2 measures,

 finally the expansion rate is about 1600.

  

Thanks

Peng
