Logging of DUR Warnings
Ignoring (Save and Continue) the DUR checking was logged in TouchScript and as of v11 TouchWorks is logged again.
The Medication_Alert table stores this information in v11.
It stores the Alert Reason (Medication_Alert.AlertReasonDE = Alert_Reason_DE.ID) and the Ignore Reason (Medication_Alert.IgnoreReasonDE = Ignore_Reason_DE.ID). Various other information is recorded as well - the Medication dictionary entry, patient, DDI, Encounter, Site, etc, etc.
The IgnoreFLAG does not appear to be populated - look at the Ignore Reason dictionary value selected.
