I read several instances where clients are getting this message and ESS seems to be the culprit.  We are a new client on HRMS, not yet set for ESS.  I just experienced this message during the PR calc but did not realize how much it affected time off balances.  Any thoughts as to why this message occurred? Possibilities found on the Knowledge Base did not apply.  I am hoping it corrects itself this next calc but am concerned it will not.  Our 3rd party is aware but am reaching out to Sage first.
