According to the stantards Auto Correlation may satisfies
only 70%.
Some times autocorrelation Didn't Identifies the string
values
Always Better to go for Manual Correlation.

Hi,
Once the script is not identified the correlation then need
to implement the manual correlation.by finding LB,RB,Ord
etc in the replay log.

Some times autocorrelation Didn't Identifies the string
values. And aslo it may not found the session id
automatically generates this may confuse to tester.

Answer / anil
The Manual Correlation or the Automatic Correlation Needs
both the Left or Right Boundaries
We will go for automatic correlation only if the particular
parameter will be occured in multiple requests and
different values in each request.
Hence we can keep the Left Boundary and Right Boundary in
automatic correlation and record the script and each
instance it will replace with a new correlation value.
Example:- when we are recording any .net application we
generally have View State and Event ID Validation then
which will be occured in almost all the requests and
different values but the left and right boundaries will be
one and same hence if we automatic this correlation
function then it will repalce all the instance properly
other we need to manually do it which takes lot of time.
Manual Correlation:- we generally use the this when the
dynamic value from the server is generated only at one
instance and you can capture it manually rather than
automating it.
Example:- Order number it will be generated only once by
the server but used in multiple places of the script.
We can also automate this also but some times this will
replace with unnecessary values in the script which is not
good and it leads to confusion, hence we will not do
automatic correcation if it in single instance
Please do let me know whether this helps you or revert back

Answer / krish..
i agree with all the above, manual correlation is best and i will suggest one thing. when you are not able to find LB n RB, then do auto-correlation, note down the LB n RB, then go for manual correlation. We can use auto correlation like this also..

Hi,
we go with Autocorrelation only when ur very sure about the
boundaries of a particular dynamic value.Manual correlation
we can do any time.
