While there is the option to download a single dimension into 50,000 rows in Analytics Workspace, downloading 50k rows including the breakdowns as it is shown in workspace would be ideal.
Why is this feature important to you -
This functionality used to be available using ad-hoc analysis and it was faster to report out to leadership. Report builder and data warehouse do not have the same flexibility as Workspace so it's not possible to get the reporting needed using another tool.
How would you like the feature to work -
Upon downloading a CSV in workspace, download 50,000 rows including the breakdowns as they are shown in workspace.
Current Behaviour -
Upon downloading a CSV in workspace, you can only download 400 rows including the breakdown. Otherwise you can only download a single dimension and see 50k rows.
