Process only one partition so you can browse the cube
If you want to browse the cube and validate dimensions, hierarchies and calculations using the data from only one partition, here is what you can do. Deploy the new cube solution, run a process structure for the cube and then process only one of the partitions. Process Structure will process all the dimensions plus mark all the measure groups as processed. That way, you can start browsing your cube with all the dimensions and one small partition processed.
