How to deploy project changes without wiping out cube data?

I have several cubes deployed with several years worth of historical data. Every time that I add a measure item or make any minor change to the cube or project from BI Dev Studio and then deploy it to the server, it wipes out all of my cube data causing me to reprocess all of the cube partitions again. Is there a way to avoid having to do this or a better way to deploy metadata changes to the cubes?

Thanks!

Hello!

I do not understand the difference or any change in behaviour since OLAP Services(7). Since then, every time you make a major structural change to a cube, like adding a new measure, you have been forced to full process the cube and all related dimensions.

Nothing have changed in SSAS2005.

|||Set the properties for your SSAS solution so that the Deployment Mode is "Deploy Changes Only" (This should be the default) and the Processing Option is "Default". If the changes are "minor", a full rebuild will not be required. Adding a new measure will require a complete rebuild of the measure group though.
