Introduction:

Hello, Thanks for stopping by my blog.

Here, in this scenario I was trying to create an automation process (Job Queue) to import files into NAV using File Management functions Move and Delete.

This function works perfectly fine when triggered on a action button but when triggered on a Job queue it throws an Error:Microsoft Dynamics NAV 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 Server.

Pre-requisites:

Microsoft Dynamics NAV

Original code

Reason for Error

• File Management functions Move uses Dot Net variable ClientFileHelper and properties as RunOnClient=Yes
• When you set the RunOnClient property to Yes, then the class instance that is defined by the variable is instantiated on the Microsoft Dynamics NAV Windows client.
• Job Queue does not support client call back from client on the server.

Resolution:

Re-code the move function of codeunit File management and set the property of Dot Net variable ClientFileHelper as RunOnClient=No

Final code:
