Hi Raj,

Instead of using current.update in both insert and update BR, please query the incident table and update the due date field.

Never use current.update in a Business Rule

You can try the below script.

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

var sla = new GlideRecord('task_sla');

sla.addQuery('task', current.getUniqueValue());

sla.addQuery('active',"true");

sla.addQuery('sla.u_fixed', "true");

sla.orderByDesc('planned_end_time');

sla.query();

if(sla.next())

{

var inc = new GlideRecord('incident');

inc.get('sys_id',current.sys_id);

inc.due_date= sla.planned_end_time;

      inc.autoSysFields(false);

      inc.setWorkflow(false);

inc.update();

}

})(current, previous);

I was wondering why do you have two different BR while you can do both operations in one itself.

Thanks

Gaurav
