Hello everyone,

I’m currently experimenting with the Trados APIs to programmatically populate a server-based GroupShare TM (GS 2020 / Studio 2021), and I’ve run into a behaviour that I’d like to better understand or confirm.

Context

• GroupShare 2020

• Trados Studio 2021

• Server-based TM created specifically for testing

• User has admin roles in GroupShare

• Importing a TMX manually via Studio works

• Importing a TMX programmatically via the API also works

However, when trying to add Translation Units directly via the API, nothing is persisted.

What I’m trying to do

I’m using ServerBasedTranslationMemoryLanguageDirection.AddTranslationUnit(...) to insert a simple TU (plain text, no tags).

Below is a simplified example of the code I’m using.
(It does not contain all variables/constants, but should give a clear idea of the approach.)

private static void Main()
{
  try
  {
    AssemblyResolver.Resolve();

    var server = new TranslationProviderServer(
      new Uri(GROUPSHARE_TM_ENDPOINT),
      useWindowsAuthentication: true,
      userName: null,
      password: null);

    var tms = server.GetTranslationMemories(TranslationMemoryProperties.None).ToList();
    Console.WriteLine($"Connection OK. Found {tms.Count} TM(s) on the server:");

    foreach (var t in tms)
    {
      Console.WriteLine($"- {t.Name} | {t.Id}");
    }

    var tmRef = tms.FirstOrDefault(t =>
    string.Equals(t.Name, TM_NAME, StringComparison.OrdinalIgnoreCase));

    if (tmRef == null)
    {
      return;
    }

    var tm = server.GetTranslationMemory(tmRef.Id, TranslationMemoryProperties.None);
    if (tm == null)
    {
      return;
    }

    var sourceCulture = new CultureInfo("en-GB");
    var targetCulture = new CultureInfo("fr-FR");

    var ld = tm.LanguageDirections.GetLanguageDirection("en-GB", "fr-FR");
    if (ld == null)
    {
      return;
    }

    var tu = new TranslationUnit
    {
      SourceSegment = BuildPlainTextSegment(sourceCulture, "Hello world!"),
      TargetSegment = BuildPlainTextSegment(targetCulture, "Bonjour le monde !")
    };

    var importSettings = new ImportSettings();
    var result = ld.AddTranslationUnit(tu, importSettings);

    Console.WriteLine($"Cached TU count: {tm.CachedTranslationUnitCount}");
    Console.WriteLine($"Actual TU count: {tm.GetTranslationUnitCount()}");
    Console.WriteLine($"TM IsReadOnly: {tm.IsReadOnly}");
    Console.WriteLine($"TM SupportsUpdate: {tm.SupportsUpdate}");
    Console.WriteLine($"Has Delete permission: {tm.HasPermission(TranslationMemoryPermissions.Delete)}");
    Console.WriteLine($"Has Add permission: {tm.HasPermission(TranslationMemoryPermissions.Add)}");
    Console.WriteLine($"Has Edit permission: {tm.HasPermission(TranslationMemoryPermissions.Edit)}");
    Console.WriteLine($"ImportResult: {result}");
  }
  catch (Exception ex)
  {
    Console.WriteLine("Error while inserting TU:");
    Console.WriteLine(ex);
  }
}

private static Segment BuildPlainTextSegment(CultureInfo culture, string text)
{
  var segment = new Segment(culture);
  segment.Add(new SdlText(text));
  return segment;
}

Output

After running this code, I consistently get the following output:

Cached TU count: 0
Actual TU count: 0
TM IsReadOnly: False
TM SupportsUpdate: True
Has Delete permission: True
Has Add permission: True
Has Edit permission: True
ImportResult: Discard-(0, xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx)-OK

So:

• No exception is thrown

• Permissions look fine

• The TM is writable

• But no TU is added

• ImportResult always comes back as Discard
