Bug 190440 Dimensions from same column will affact each other.[1101]
Description: Dimensions from same column will affact each other. Build number:2.2.0.v200706011658 Steps to reproduce: 1. Open attached report. The cube in the report contains "static amount" and "interval amount". 2. Preview the report. 3. Delete interval amount group and preview again. Expected result: Step2 and step 3 display same effect.
