if (atoi(lr_eval_string("{SecurityToken}")) > 0)
    {
        lr_end_transaction("01_Cards",LR_PASS);
        lr_output_message(lr_eval_string("Value of Security Token is : {SecurityToken}"));
    }
    else
    {

Your management owes you training and a mentor. You may find this statement infuriating, but it is your management who is setting you up for issues. This is from someone with two decades of experience in this field and who has over a thousand answered questions per year online on the topic of performance testing with and without LoadRunner involved. You can also find a podcast which is directly related to this discipline at http://www.perfbytes.com

Virtual Table Server is the mechanism to do this in LoadRunner. If you do not want to use VTS then you can use other service brokers to handle this. Solutions have been built around MYSQL, RabbitMQ, ORACLE and SQL Server Queue Tables, etc... The architecture of this solution is Virtual user A writes to a queue. Virtual user B, which you are trying to pass the data to, "pops" the next value from the queue. The service oriented architecture of the queue handles the appropriate managing of lock for push onto the queue and pop from the queue for multiple users.

What you cannot do successfully is write to a common file or to a parameter file for another user. This will not work for a half a dozen different reasons related to locking on multiple user access for read/write and delete as well as when and how the parameter files are loaded and addressed by virtual users.

Straight away you can't pass one script data in another script, below are alternatives to reach your goal,

  1. Use VTS to share data among scripts.

  2. Merge two scripts into one script.

  3. If possible prior to the load tests, create test data and seed them in script.
