I am new to SSAS, and exploring Partitioning. My data source is very large (web logs):a few hundred million records.

I would like to define my cube IN BIDS, and create a SSIS Package to create partitions. For now, I am Generating The MDX to Create & process the partitions, and Executing them in SSMS. 

I find that this is faster and less error prone them manually creating the partitions using the BIDS UI. 

I am trying to understand the expected workflow: because every time I go back to BIDS, and make changes to measures & process the cube the partitions I created in SSMS are deleted and the old partitions I created in BIDS are re-published.

What I would like to be able to do is Refresh my partitions from the server to BIDS. Is This possible? If not, what type of workflow is expected in this case? 

Thanks!
