SOAPUI Loadtestrunner

Hi,

I am new to soapui and would like to test application with soapui loadtestrunner. I already have testcases setup with soapui.

Here is my concern,

1. the filings that I am submitting generates unique id.. now in case of load testing when i increase no. of users (by increasing no. of threads from default 5)  - how it's going to generate unique filing id for each submission ?

2. If this scenario is not possible is there any other way round for this ? i.e. any way loadtestrunner can generate dynamic value for each filing id ?
I have not received any feedback.. please advise.


Thanks in advance.
