Calculations with External Aggregates (Non Additive Calculations)

Calculations are built from the underlying data fields within the dataset.  For additive datasets, aggregates of calculated fields are either based on:

q  A defined aggregation method, using the leaf calculation, and aggregating this up the hierarchy.

q  The Calculate aggregation method, using the sum of each term in the formula, up the hierarchy.

In the case of external aggregates, and applying the Calculation aggregation method, calculations will use the external aggregate values for each term within the formula, when calculating up the hierarchy.
