问题
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!

Partitions are part of the cube structure, and if you change these outside of BIDS, then you change the structure of the deployed Analysis Services database. BIDS keeps the definition of the structure locally as a set of XML files, the partition definitions are contained in a file with the extension .partitions. If you deploy an Analysis Services project from BIDS, it updates the deployed Analysis Services database to match the structure of the local XML files, thus overwriting whatever you changed outside of BIDS.
You can get a deployed database back to an Analysis Services project as follows: Open BIDS, click File/New/Project, and then select "Import Analysis Services Database" from the "Business Intelligence Projects" project type, and select the directory where you want to save the project files locally in the bottom part of the dialog. As soon as you click OK, a wizard opens that allows you to select the server and Analysis Services database to get the definition from, and when you click Next, starts writing it to the directory that you selected.

Partitions are a part of your cube structure. You should create the partitions in BIDS and then process them based on your requirement using SSIS or SSMS.
