Hi,
There are several ways you can create files to store responses which can be used at a later stage from anywhere. For example, you could try to use DataSinks for this purpose:
http://www.soapui.org/Data-Driven-Testi ... sinks.htmlOr even a Groovy script (see
http://www.soapui.org/Scripting-Propert ... ricks.html and
http://amadei.com.br/blog/index.php/wri ... rom-soapui).
Save these files in a location you can easily refer to (use a global property to save the directory name, which can then be pointed at from just about anywhere in SoapUI).
You can then refer to the saved files quite easily using a File Data Source (
http://www.soapui.org/Data-Driven-Testi ... files.html), for example, or, again, a Groovy script.
Good luck and let us know if you need more assistance,
