In our project we have a mapping with 6 to 7 lookups,6 joiners, 10 aggregators,deduplicator and lot expressions. The problem here is it is occuping lot of temp segment.so i am getting error as temp segment can't be extended.. so the mapping comes out.

now i have to tune the mapping so that it should reduce using the temp segment.

pls help me out to tune this

Regards,
Vasu

First of all, split up the mapping in smaller parts and use some tables in which you can store sub results.
