Hi @nameisnani 

The non code way to do this is Assignment rule . 

or by OnChange client script you can achieve the same. 

In case of On Change client script; you need to create a  script on change of "Service" in the script section add If logic to check if newValue == < the service you are trying to apply the logic for > 
{
set value for assignment group field ( get value - service.supportgroup)
}

Kindly mark the reply as a correct answer / helpful if it helped to solve your question.

Thanks,

Hi @nameisnani 

You can create onChange client script for change request table with field as "service". Below is the code

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
    if (isLoading || newValue === '') {
        return;
    }

    if (newValue) {
        var ga = new GlideAjax('ajaxUtils');
        ga.addParam('sysparm_name', 'getServiceSupportGroup');
        ga.addParam('sysparm_serviceId', newValue);
        ga.getXMLAnswer(callSupportGrp);
    }

    function callSupportGrp(answer) {
        var supportGroupId = answer;
        g_form.setValue('assignment_group', supportGroupId); // set the field name correctly as per your field name
    }
}

Script Include(client callable)

var ajaxUtils = Class.create();
ajaxUtils.prototype = Object.extendsObject(AbstractAjaxProcessor, {

	getServiceSupportGroup: function(){
		var sprtGrp;
		var serviceId = this.getParameter('sysparm_serviceId');
		var grService = new GlideRecord('cmdb_ci_service'); // service reference field table name
		if(grService.get(serviceId)){
			sprtGrp = grService.support_group;
		}
		return sprtGrp.toString();

	},

    type: 'ajaxUtils'
});
