Answer / jaimeen shah
You can configure the Update Strategy transformation to
either pass rejected rows to the next
transformation or drop them based on the update strategy
expression. By default, the PowerCenter Server forwards
rejected rows to the next transformation. The PowerCenter
Server flags the rows for reject and writes them to
the session reject file. If you do not select Forward
Rejected Rows, the PowerCenter Server
drops rejected rows and writes them to the session log file.

Answer / kondareddy
for example take one condition in update strategy
source we have 20 records. in that records we have 4 records has less then 500 salary
in update strategy condition is
iif(sal<500,3,sal) based on that condition only 15 records stored into target. so it will be effected on rows. becoz in update strategy 3 indicates rejected records....
so it is active....
