What is aggregate awareness? What is its advantage.
ggregate awareness function is used in scenarios where we have same fact tables in different grains. Using this function we can define only one object for the measures in the fact tables as
We also need to define dimensions for associated granularities and define their incompatibilities with the corresponding facts through the aggregate navigation. This is accesses through Tools -> Aggregate Navigation
The advantage is that in a Webi or Deski report when one drags the measure object with the dimension object of a particular granularity, the measure column from the Fact table of the corresponding granularity is selected in the BO default Query. If we did not use aggregate awareness, we would need to define separate objects for each of the fact tables which would be difficult to understand from a user’s point of view.
