Advanced Search Results not containing Record InternalID

Hi All,

I have an advanced search which is pulling results from a UI search correctly, however the InternalID field which is on the search is not being retrieved, I need this ID as once the data is retrieved I need to mark a field to say that record has been processed.

Can anyone advise why this custom record search does not retrieve the Internal ID into the web services request.

 private void executeSavedSearch()    CustomRecordSearchAdvanced wpaRecordSearch = new CustomRecordSearchAdvanced();    wpaRecordSearch.savedSearchScriptId = "customsearch_wpa_auto_ddl_data_request";  SearchResult searchResult = service.search(wpaRecordSearch);    if (searchResult.status.isSuccess)  {Console.WriteLine("Search WPA Success.");  }    else   {Console.WriteLine("Search WPA Failed.");  displayError(searchResult.status.statusDetail); }    Console.ReadLine();  }
