Hi,
In LoadRunner version 12, you can automatically correlate the dynamic values.
After stop recording the script, Vugen will process Correlation Scan to find the dynamic value that you should correlate.
Or you can click on Design Studio button to process Correlation Scan, then with the value that you want to correlate, you click on Correlate button. Please refer the Design_Studio image.
If you want to correlate the value manually, you can find the value by checking on Output tab/ Code Generation and Snapshot tab/ Response Body. Please refer the attached images.
And you can find Step Navigator or Snapshot in View tab or they also display in button format. I highlighted these buttons in the attached images.
For more information, please refer HP LoadRunner User Guide- page 187 - Correlation Studio.
Please feel free to let me know if you have any concern.
Regards,
Chau
