How to clear list type field in business rule

[Nico12]

Hi,

I am trying to empty a list type field value in a business rule but gr.fieldname = '';  doesn't seems to work.

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

	// Add your code here
	var approvers = [];
	var getApprovers = new GlideRecord('sysapproval_approver');
	getApprovers.addEncodedQuery('source_table=sc_req_item^state=requested^sysapproval=' +current.sysapproval); //only show pending approvals on sc_request and sc_req_item tables
	getApprovers.query();
	while(getApprovers.next()){
		approvers.push(getApprovers.approver.toString());
		var taskValue = getApprovers.getValue('sysapproval');

		var getRitm = new GlideRecord('sc_req_item');
	//getRitm.addQuery('request',current.sysapproval);
	getRitm.addQuery('sys_id', taskValue);
	getRitm.query();
	if(getRitm.next()){

		getRitm.u_approvers = '';
		getRitm.u_approvers = approvers.toString();

		getRitm.update();
	}	
	}

})(current, previous);

Hi,

Try using 
getRitm.setValue('u_approvers', '');

Although, you are just setting new values to the list field, you donot need to explicitly empty the field, just remove this line from the above script:

getRitm.u_approvers = '';
