Mass Updating Delivery Parameters Hi Team,I am writing a script to mass update parameters such as Sender Address and Reply Address from the Deliveries schema. Additionally, I need to update the Routing (External Account) of Delivery Templates, but I'm unable to do so as the value does not get updated when using the Routing Primary Key.Moreover, I want to exclude OOTB Delivery Templates to ensure they are not modified or updated.Below is the script I am using:var delivery = NLWS.xtkQueryDef.create({queryDef: {schema: vars.targetSchema , operation: 'select',select:{node: [{expr: '@id'},{expr: '@from'},{expr: '@reply'},{expr: '@extAcct'},]}}});var results = delivery.ExecuteQuery();for each (var res in results.getElements("query")){delivery = NLWS.nmsDelivery.load(res.getAttribute('id'));delivery.mailParameters.senderAddress= res.getAttribute('from');delivery.mailParameters.replyAddress= res.getAttribute('reply');delivery.deliveryProvider.id= res.getAttribute('extAcct'); delivery.save();}I need help with the following
