Release Any supported release. Cause Duplicate entries created in 'sys_history_line' table, when the users are viewing the audited (for example incident) record, but having different domain / Date format / Language / Time Zone. This is expected design behavior, because new sys_history_set would be built based on the domain / Date format / Language / Time Zone of the user. Resolution Though the sys_history_line record appears as duplicate, actually they are not, as they will have different set field ('sys_history_set'), this is an expected design behavior.
