Frequency of Use of OpenCDISC Validator

Hi Everyone,

I am looking for suggestions as to when to run OpenCDISC. I know that we will run it before data reviews and at DBL. 
However, I was wondering if anyone is re-running it prior to submission? The thought being that a newer version of OpenCDISC Validator, with a new rule configuration was updated and we would want to see results before the FDA runs it.

Any feedback would be appreciated.

Thanks,

Jim Miller
