Hi Everyone,
Can we add a dimension to an existing cube? If not, why can't we do so?

Performance Modeller allows you to do so but you need to obviously map all of your existing values to just 1 element in the new dimension and you need to be careful of the implications on rules for that cube and any associated TI processes in or out.

Its often easier/more robust to just ascii out your old values and build a new cube.

If you go the PM route though i haven't done it in a while but think you just open the cube view and then drag your new dimension over to a row/column etc.

Thanks Declanr.

It was noted in a previous thread that for you to do this via PM, the target cube has to be very small otherwise it kicks up errors.

If you have quite a lot of data in it, best to do as above.
