NAV 2013 NAS File Import Call back Error

NAVPRAKASH

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

Hi

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

Thanks.

NAVPRAKASH

I'm using Build 7.00.34216

NAVPRAKASH

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 ?

I also got same error in my local system too

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

I am also facing same problem. Is there any solution?

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
