Attaching the knowledge article from parent incident to child incident automatically

[Nafisa Zaman]

Attaching the knowledge article from parent incident to child incident through script. But when i am creating new child incident Duplicate KB article is attaching. Please guide me why this is happening

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

// // Add your code here

// if(current.task.sys_class_name == 'incident')

var parent = current.sys_id;

var inc = new GlideRecord('incident');

inc.addQuery('parent_incident', parent);

inc.query();

while(inc.next())

{  

var kn1 = new GlideRecord('m2m_kb_task');

kn1.addQuery('task',kn1.task.p);

kn1.initialize();

kn1.task = inc.sys_id.toString();

kn1.kb_knowledge=current.u_ka_attached;

kn1.insert();  

}

})(current, previous);

Hello @Nafisa Zaman 

Modify your script with mine :-

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

// // Add your code here
// if(current.task.sys_class_name == 'incident')

 
var parent = current.sys_id;

var inc = new GlideRecord('incident');
inc.addQuery('parent_incident', parent);
inc.query();
while(inc.next())
{  
var kn1 = new GlideRecord('m2m_kb_task');
kn1.addQuery('task',kn1.task.p);

kn1.initialize();
kn1.task = inc.sys_id.toString();
kn1.kb_knowledge=current.u_ka_attached;

kn1.insert();  
var attach = new GlideSysAttachment();
attach.deleteAll(current.sys_id);

}
 

})(current, previous);

Plz mark my solution as Accept, If you find it helpful.
