NetSuite SuiteTalk ReturnAuthorization - return

Question

I am trying to create a Return Authorization from a Sales Order but can not determine the required parameters.
I keep receiving an error of:
You must enter at least one line item for this transaction.
If I attempt to include the id of one of the line items in the sales order I receive the following error:
Savon::SOAPFault ((soapenv:Server.userException)
com.netledger.util.schemabean.NLSchemaBeanException: id not found on
{urn:customers_2016_2.transactions.webservices.netsuite.com}
ReturnAuthorizationItem
This is my current request

Answer 2

You have to create a initialize for the same.
So once the Sales order is created then we can do a Authorization Return on it once it successfully goes through the process.
More info at : https://docs.oracle.com/en/cloud/saas/netsuite/ns-online-help/section_N3508536.html
Make sure the SOAPAction is set to initialize.
