⟩ When we use aggregate awareness function in designer?

1. In order to solve fan trap in busines objects we either create alias table or aggregate awareness function

2. Through aggregate navigation we can also select the compatable as well as incompatable objects

Ex:-year, quarter, month, week, day

year:-quarter, month, week, day are compatable objects

quarter:-year?class is incompatable and month, week, day are compatible.

3. We specify the objects in descending order.
