 Use this Script in Business Rule

var task= new GlideAggregate('incident_task');
task.initialize();
task.parent = current.sys_id;
task.incident = current.sys_id;

task.insert();

Thanks for replying @Kishore Aregila

There may have been a miscommunication, let me clarify what I meant. My requirement was quite different I meant to say that once I click on "new"  button in the related list of Incident form to create a new Incident Task then one of the field in Incident Task form named 'incident' must auto-populate its value with the parent Incident number. Like if Incident form has Incident number: INC00000101 then the incident task form must auto-populate this value in its incident field on load.

I had written a client-script for this and it worked for me.

Client Script:

Table: Incident Task

Type : onLoad

function onLoad() {

var gURL = new GlideURL();

gURL.setFromCurrent();

var incidentNum = gURL.getParam("sysparm_collectionID");

if(incidentNum!=undefined) {

g_form.setValue('incident',decodeURI(incidentNum));

}

}
