How to do correlation when the boundaries are dynamically changing?

Loadrunner

Consider a scenario when the Left and Right Boundaries are dynamically changing, using which we will have to capture the correlation value.

1. If the LB and RB has dynamically changing numbers:

Then your LB and RB becomes LB/DIG & RB/DIG and replace the dynamically changing numbers in the boundary with #.

Example:

Iteration 1: City001"Chennai"001City
Iteration 2: City002"Bangalore"002City
Iteration 3: City003"Delhi"003City

Here we can see that LB and RB are getting incremented from 001 to 003. So, our boundary becomes

LB/DIG = City00#\"
RB/DIG = \"00#City

2. If the LB and RB has dynamically changing alphanumeric values:

Then your LB and RB becomes LB/ALNUM & RB/ALNUM and replace the dynamically changing alphanumeric values in the boundary with ^.

Example:

Iteration 1: Citya01"Chennai"a01City
Iteration 2: Cityb02"Bangalore"b02City
Iteration 3: Cityc03"Delhi"c03City

Here we can see that LB and RB are getting incremented from a01 to c03. So, our boundary becomes

LB/ALNUM = City^^^\"
RB/ALNUM = \"^^^City
