Update the 'Parent Incident' field on child of child Incident

[Delapan]

If you are trying to link a parent incident under the child Incident, the child incidents should be re-parented to the Incident you are on.

Example: If you are going to add INC2 as child Incident of INC1, but INC2 has 2 child Incidents (INC3 & INC4). When you link INC2 as a child to INC1, then INC3 and INC4 should get re-populated to INC1.

How can we achieve this.

Thanks in advance.

Hi @Delapan ,

You can do it with the below business rule :

(function executeRule(current, previous /*null when async*/) {

    if (current.parent.nil() || current.parent == previous.parent) {
        return; }

    var childIncidents = new GlideRecord('incident');
    childIncidents.addQuery('parent', current.sys_id);
    childIncidents.query();
    while (childIncidents.next()) {
        childIncidents.parent = current.parent; 
        childIncidents.update(); 
    }

})(current, previous);
