Giscard,
Thanks for the DataSource info. My situation is a little different. The param I am using is not for the data (i.e., ID) in default soap request (in this case, you can click on Request data box and "Get Data" to connect to DataSource). My xml request (send to Queue) content is manually written (see screen). "Entry_No" is the param name. There is no "Get Data" window options for connecting my param to DataSource file.
I can set param value in testcase-property window but that is single value. What I need is "Entry_No" needs to pick up different value when run load test. Hopefully I explain my problem clearly.
Thanks,
Larry
