Generate a unique filename

Hi Guys,

I'm trying to call a web service that requires a unique filename for each request.

I've created a DataGen Test Step, and suspect that I can script something here, but I'm not quite sure how. Can someone give me a hand please.

I can tell that in the SOAP request itself I would just use something like ${DataGen#Rand1} .. but what does the script in Rand1 look like?

Thanks
Warrick
