Add a handler to `custom_before_cancel` event:

	cur_frm.cscript.custom_before_cancel = function(doc) {
	    if (user_roles.indexOf("Accounts User")!=-1 && user_roles.indexOf("Accounts Manager")==-1
	            && user_roles.indexOf("System Manager")==-1) {
	        if (flt(doc.grand_total) > 10000) {
	            msgprint("You can not cancel this transaction, because grand total \
	                is greater than 10000");
	            validated = false;
	        }
	    }
	}
