[Update June 29, 2017]
This article also explains a similar action for withdrawn Violation Reports due to an ICOTS release on May 31, 2017.
With the launch of ICOTS Release 18.0, any pending violation reports or responses to violation reports had to be withdrawn or deleted when the release wen live on the morning of 5/22/2013. If an OVR or RVR was withdrawn, it was done by Appriss' super administrator account, which happens to be assigned to Alabama.
If you see that in the activity history that an OVR or RVR was withdrawn on 5/22/2013 by an Alabama user and Alabama isn't associated with your compact case, there is nothing wrong with ICOTS.
Any violation report that didn't have a transmitted response to violation report before 3am on 5/22/2013 will need to be resubmitted using the new violation process.
