Below is sample code to perform a TransactionSearchAdvanced from an existing saved search using the search Operation. Please note this will require a valid login session. Please note this operation is successful with using the WSDL prior to 2013.2.
Status s = nss.login(passport).status;
if (s.isSuccess == true)
// Creating the TransactionSearchAdvanced Object and assigning the saved search id to the object.
TransactionSearchAdvanced tsa = new TransactionSearchAdvanced();
// Passing the ID of the saved search that exists in NetSuite.
tsa.savedSearchScriptId = "customsearch7";
// Passing the TransactionSearchAdvanced object to the NetSuiteService Object.
SearchResult sr = nss.search(tsa);
//Displaying the number of records return if the search was successful.
