Correlation is used to obtain data which are unique for each
run of the script and which are generated by nested queries.
Correlation provides the value to avoid errors arising out
of duplicate values and also optimizing the code (to avoid
nested queries). Automatic correlation is where we set some
rules for correlation. It can be application server
specific. Here values are replaced by data which are created
by these rules. In manual correlation, the value we want to
correlate is scanned and create correlation is used to
correlate.

Answer / illur iqbal

Correlation is a method of capturing values in a script as
a result of dynamic data passed from the server to the
client and back. the values are saved in the Load runner
parameter and is reused instead of original recorded value.

Thanks.......Illur Iqbal

Answer / manoj kumar

correlation is a process to handle the data which is dynamically generated by the server.for the server generated values we will do correlation.
manual correlation:-
without using the automated features we will do correlation for server generated values in 3 steps.
step 1:- identify the captured values in recorded script by using wdiff.
step2:-capture the value and save it into variable by using web_reg_save_param function.
step3:-replace the variable in place of identified correlated value.
Automated correlation:-
we will do correlation by using the design studio and correlation rule
