5. Upsert row to a Data Extension

5_UpsertDE.js

//UPSERT DE
var co = {
    "CustomerKey": "7254CCBC-E5F8-49B6-991E-855825DAEADD",
    "Keys":[
        {"Key":{"Name":"subscriberkey","Value":"test@fakeemail.com"}}],
    "Properties":[
        {"Property":{"Name":"color","Value":"purple"}}
      ]
  };

var uo = {
  SaveOptions: [{"SaveOption":{PropertyName:"DataExtensionObject",SaveAction:"UpdateAdd"}}]
};

SoapClient.update('DataExtensionObject',co,uo, function(err, response){
  if(err){
    console.log(err);
  }
  else{
    console.log(response.body.Results);
  }
});

How can we upsert rows without primary key-value data extension?
