Note 1: OBIEE offers two calculation types for measure in the repository:

logical

physical

You can define calculations in either of the following ways:

* Before the aggregation, in the logical table source.

* After the aggregation, in a logical column derived from two other logical columns. For example: sum(col A) * sum(col B)

Note 2: A measure column is a column unlike the baseline column that has a default aggregation rule defined in the Aggregation tab of the Logical Column dialog in the repository.

Measure columns always calculate the aggregation with which they are defined.

Measures need to be defined in a logical fact. Any column with an aggregation rule is a measure.
