Hello, Does any one know why a date field keep disappearing from online RPD? we have added "Promised Date" to the RPD below in green box, after the RPD deployed, it is ok for a few days, but after a few day later, when we check the online RPD, the field disappeared, but then check the offline RPD, it is still there. so we re-deploy the RPD again, and it works for a few days, then disappeared again, this keeps repeating …. does any one know why? the same change has no issues in non-prod, only happened in PROD. this is OBIEE 11.1.1.9. appreciate your help! thanks!
