Purging Obsolete Open SOs

SUGGESTED

I'd like to clean up open SOs our test environment.  We have hundreds of SOs in test due to site scraper software pulling in orders from our online store.

Is the Purge Obsolete SO utility the way to go?

And do people need to be out of our production environment to run utilities in test environment?   I tried to run utility and received an error that SO data entry was preventing it from running - which is only occurring in production now.

Or is there a better way?

Thanks.
