I stumbled on this today so forgive me if this is mentioned elsewhere or is too obvious…
Data Cubes do not have a Save As… option like dashboards. But I have a data cube that I only need to make one change to but I don’t want to reinvent the wheel, what do I do?
Use the Explore window, right-click the data cube, select copy, and paste a copy of it back into the folder (or a different folder). It saves all of dimensions associated with your cube so all you need to do is rename it and then use the rewire feature Taking Advantage of the Re-wire Feature in Dundas BI to point the metric set to the newly copied data cube.
