str     filepath = @"D:\";

System.IO.FileStream fs;

    The issue is that you are trying to use str filepath = @"D:\"; as a filepath, but AX7 is hosted in Azure and cannot access files on your local drive in that way.

    Depending on your scenario, you would either need to upload file to docuRef table via FileUpload control in AX7(You can use File::GetFileFromUser() or create new dialog with FileUploadStrategy class), or if you need to create new file, from some data, you need to initialize System.IO.MemoryStream to work with memory.

    Also, you can get Stream from docuValue with Documentmanagement framework.

    Please see this link about document upload control:

    Hi guruprasanna,

    What is the business requirement to access local drives? In a production environment, you don't have access to the machine, so why are you trying to access local drives? Is it because of temporary files? Please elaborate.

    Hi Fedir Kryvyi and André Arnaud de Calavon,

    Thanks for the reply, I have checked those links. But my requirement is to export the on-hand item quantity details to text file(including all company details in single file),  i have exported this to azure drive and I wanted to give browse link to user so that they can download the text file. Can you please tell how can we achieve these type of requirements. 

    Thank you in advance
