How to auto-populate incident number of incident table to incident field of incident_task table ?

You can create after business rule on Incident task table. Your business rule should run on Insert and Update

Please make sure to check advanced checkbox.

(function executeRule(current, previous /*null when async*/) {
	
	var nmr = new GlideRecord ('incident'); // Incident Table

      nmr.number   =  current.<incident field of incident task table> ;

      current.update() ;

})(current, previous);

Thank you @Alp Utku  for replying.

It seems without having any query statement It may not return the required record.  

My requirement is to auto-populate incident field of incident_task table. 

You can follow the below attachments.

You are right, you need to add query statement to fetch number from the Incident table

Yes, I can write a BR to fetch the number from the incident table, but I want to know how can I use this fetched data on another table like incident_task table. 

I want to set value of incident_task table incident field with the value of its parent table ( i.e incident ) number field.
