⟩ 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.
