Using Visual Studio 2008, targeting SQL Server 2008 R2.
1. Within SSIS package add Analysis Service Processing task
2. Add processing step to this task (within Processing Settings section) and make it to be an Incremental update of some partition.
3. Save this package and reopen it later
4. Add one more step to the same Analysis Service Processing task.
5. The existing step (created in p.2) automatically turns to Full update. It is not incremental anymore.
Looks like some kind of bug to me. Did anybody see this? Is there any workaround?
