What is a baseline column ?
Dimensional Data Modeling - Descriptif Attribute (Dimensional Attribute) in OBIEE.
A baseline column is a column unlike the measure column that has no aggregation rule defined in the Aggregation tab of the Logical Column dialog in the repository.
The BI Server don't see it as a measure and then add it of:
- in the GROUP BY clause
- of in a ROW_NUMBER function
in the physical sql generated in order to preserve (of augment) the grain of the logical SQL
