When Kb article is flagged and add comments, an idea notification is getting triggered after upgrade to New YorkDescriptionAfter upgrade to New York there is a new plugin called Innovation Management will get activated and triggering Idea activity notifications for comments added in flagged KB. More about Innovation Management plugin Click HereRelease or EnvironmentNew YorkCauseWe have a subscriptions for KB and Idea core Fanout'swhen ever any KB is commented an activity get's created in sn_actsub_activity table.sn_actsub_activity table have a BR which triggers all fanout's in fanout table.BR is "Fanout Tasks"When ever idea_activity fanout is initiated, it should check whether that particular record belongs to idea or notIf it is idea then only it should process idea_activity, other wise it should notIf both Idea and KB Fanout's active and the idea fanout listener is missing the check to detect whether that record is a child of im_idea_core or not, it is triggering the event and email.since it is missing the check code inside the script include "IdeaActSubService" it is triggering the im_idea_activity.commented and triggering that idea notifications.ResolutionIdeally, simply disable the "Notification on Comment to an Idea" email notification record by setting "Active" to 'false'. /nav_to.do?uri=sysevent_email_action.do?sys_id=785182bd77047300d82ea3334a106162%26sysparm_view=advancedAn alternative workaround/fix for this issue is to add a piece of code in the script includeOpen script include -: 'IdeaActSubService'Inside the 'processActivity' Method, Please add the below condition. (Condition to be added inside try block, after first two if conditions - This condition needs to be added) tableName = current.getElement("target_name");if(!this.isChildOfIdeaCore(tableName)) return; So, This shouldn't trigger - im_idea_activity.commented event. Hence, email notification will not trigger. Note: Please try this workaround in any of your sub-prod instance and then try to implement in your production instance.
