Further to Past Thread on Child activity only able to access Parent Work Item only to a single level i-e SeedRole='target' cannot be used twice.
However it is noteworthy that Parent Item can access child items up to two levels. I-e from Service Request -> Child Activity -> About CI ->Display Name (you can note /Path[RelationShip used twice)
So it seems that if notifications can be configured on Service Requests instead of Activities can work in some cases where the criteria for email can be defined at that level.
$Context/Path[Relationship='CustomSystem_WorkItem_Activity_Library!System.WorkItemContainsActivity 'TypeConstraint='CustomSystem_WorkItem_Library!System.WorkItem']/Path[Relationship='CustomSystem_WorkItem_Library!System.WorkItemAboutConfigItem'TypeConstraint='CustomProvance_ServiceManager_Itam_Core_Library!Provance.ITAM.Location']/Property[Type='CustomProvance_ServiceManager_Itam_Core_Library!Provance.ITAM.Location']/DisplayName$
However i am unable to extend the same concept to another Query String to use it three times /Path[RelationShip OR! i hava a mistake in my below query string syntax as in output rendered is the querystring as is without a result (which is often a problem)
$Context/Path[Relationship='CustomSystem_WorkItem_Activity_Library!System.WorkItemContainsActivity' TypeConstraint='CustomSystem_WorkItem_Activity_Library!System.WorkItem.Activity.ReviewActivity']/Property[Type='CustomSystem_WorkItem_Activity_Library!System.WorkItem.Activity.ReviewActivity']/Path[Relationship='CustomSystem_WorkItem_Activity_Library!System.ReviewActivityHasReviewer' TypeConstraint='CustomSystem_WorkItem_Activity_Library!System.Reviewer']/Property[Type='CustomSystem_WorkItem_Activity_Library!System.Reviewer']/Path[Relationship='CustomSystem_WorkItem_Activity_Library!System.ReviewerIsUser' TypeConstraint='CustomSystem_WorkItem_Activity_Library!System.User']/Property[Type='CustomSystem_WorkItem_Activity_Library!System.User']/Id$
I need to access : ServiceRequest->ReviewActivity->Reviews->IsUser->Email Address
Any help would be appreciated.
