Cube Calculation vs Cube Metric Accounts

Question

What is the difference between a cube calculation account and a cube metric account?

Answer

Cube Calculation accounts and Cube Metric accounts primarily differ in the way in which they roll up data. There are also performance benefits to Cube Calculation accounts, since they will not attempt to evaluate in every intersection automatically, whereas a Cube Metric account will automatically evaluate for all possible intersections.

Cube Calculation
accounts roll up data in the same way that standard custom accounts do: by default they sum at level, dimension, and time rollups. However, it is also possible to change their roll-up type as needed to "average" or "weighted average".
Cube Metric
accounts roll-up in the same way as standard Metric accounts, and are often used for financial ratios. In roll-up periods, they re-evaluate the formula rather than summing the calculation in each contributing month and level.
