Thanks in advance.


  • __CSVRead() function.
    You will not be able to use CSV Data Set Config as it is a Configuration Element and according to the JMeter Test Elements Execution Order all the configuration elements are being initialised at the very beginning of the test while your requirement is to read data based on user dynamically.
    Check out How to Pick Different CSV Files at JMeter Runtime article for comprehensive information on using __CSVRead() function
