Description

The issue can be reproduced by the following steps:

1. Create a model with fact table and lookup table(s)

2. Create a cube with derived dimension(s) on lookup table, it will build snapshot during the building

3. Build the cube with a time range, 2011-01-01 to 2012-01-01 for instance

4. After building finished for the first segment, build a segment with an earlier time range, 2010-01-01 to 2011-01-01 for instance

5. Before snapshot built for the earlier segment, do a query on the snapshot (for instance, select * from lookup), no realiztion found exception will be thrown
