There r 3 ways of correlating in Manual section.

We usually use the 3rd Option -Vuser Comparison

1)Record 2 scripts with the same actions.
2) Compare these 2 Scripts with Compare option in the Tools. ) This will show all the Dynamic Values, make a note of this in notepad.
3)Close one of the Scripts and go to Tree View - Server Response.
4) Now Click on the Page which you need to Parametrize(Yellow icon is the symbol for Page).
5) You'll find HTTP Response under which you'll find Body - Expand Body, Expand Application Name, Expand Application Navigation Bar, Expand Form, You'll find "act" click on the "act.
6) Now you'll notice a line is highlighted. The value below is selected and Right Click and say Replace with a Parameter.
7) This will include a new Service in the Tree View and a function in the Script as web_reg_save_param.

This should work :)

Hi All...,

Manual Correlation in LoadRunner is very simple to do in LoadRunner if you follow these steps :

1> Need to find the server generated id in the script which we need to correlate
2> After you found the server generated id Goto the Previous request
3> Place the cursor before the previous request
4> Goto the Server Response
5> Find the server generated id in the Body left side and expand body
6> search with server generated id in each and every element of the Body
7> After you found the server generated id you need to select the left and right boundaries
8> And also you have to find that the server generated id is available which occurrence i.e.,ORD value
9> Then again redirect to the script and write the correlated function before the previous request
10> And final step is to replace the server generated id with variable which we have specified in the correlated function

  1. web_reg_save_param("SessionID",

  2.                                "LB=value=",

  3.                                "RB=>",

  4.                                "ORD=1",

  5.                                 LAST);

Manual Correlation: This can be done in 3 ways:
1) Manually check the script: Correlate the dynamic values going thru the script.
2) Snapshot comparison: Compare the snapshots for the Recording & replay
3) Script Comparisons: Record the same script 2 times and compare the scripts for dynamic values thru Tools> Compare with Vuser option in VuGen.
