NAV 2013 NAS File Import Call back Error

Dear Experts

I’m trying import txt file using NAS. NAS throws the Call back error while using the standard SlientUpload function. I have tried in RTC Client for importing the file, NAV repeatedly asked confirmation dialog to access the File every time in a new NAV session. I have overcome the confirmation dialog using the “ServicePrincipalNameRequired” = true in the user ClientUserSetting. After this setting it stopped asking confirmation in RTC Client. But It seems the same confirmation is comes in the NAS too. This was reason for error in the NAS Import. I have tried to create SPN for the Domin user. Any special setup is required in Config file for this? Any suggestion is highly appreciated.

The below message for Event Log

The Microsoft Dynamics NAV Application Server session has failed. Reason: Type: Microsoft.Dynamics.Nav.Types.Exceptions.NavNCLCallbackNotAllowedException
SuppressMessage: False

Message: Microsoft Dynamics NAV Application Server attempted to issue a client callback to create a DotNet object: System.IO.File (CodeUnit 419 File Management). Client callbacks are not supported on Microsoft Dynamics NAV Application Server.

    Hi

    I'm also facing the same issue. Can you please let me know the Navision 2013 Build that you are using?

    Thanks.

    Does any special Permission is required in the Windows for calling the .Net Variables without Permission Dialog Confirmation or something related to SPN permission ?

    I have created simple CU with two lines of Code

    FileName := 'C:\T1\T.TXT';
    FileName2 := FileMgt.UploadFileSilent(FileName);

    I have executed this CU through NAS

    The File didn't uploaded and below error logged in Event Viewer. I hope many people have already tried File Import in NAS.

    What I'm missing here ?

    As I read your question, you are running the code on the NAS in the service tier.
    The upload function reads a file from your client computer to the server. But when the code is executed from the NAS, there is no client - the dotnet exception also mentions that call-backs to the client is not possible - because there is no client.
    So if you intend to read the server's file directory, e.g. C:\temp\a.xml, then just read it as is. You haven't listed the exact scenario, but if it e.g. was an XML document, you would just write something like xmldom.load('C:\temp\a.xml'); or if it is something else, you can read it with a file variable: MyFile.OPEN('C:\temp\a.xml');

    I'm using the same Codeunit for both Manual run and NAS import purpose . So believe I have to use GUIAllowed in this case. Thanks for clarificatiion

    You should look in CU419 and you have to use appropriate DotNet Variable e.g NAV2017 DirectoryHelper has property RunOnClient set to Yes, which throws Callback error, while DotNet Variable ServerDirectoryHelper works fine on Server with Job Queue
