what is the difference between aggregation and role up aggregation ?
Answer Posted / suresh
Hi,
Aggregation is normal aggregation like we do in SQL
query(Total,Avg,Count,Max,Min,Sum).
Rollup aggregation is at the end what should do for the
total report.
for example below:
Country Quantity
India 10
India 24
Singapore 6
Malaysia 4
when you group this report Aggregation for India
34,Singapore 6,Malaysia 6 and Rollup aggregate for this
report will be 44 calculated
