Hi Experts,

I am facing the issue that I have been asked that I should add the factbox under the Attachment Tab. But I am able to add it under the Details Tab. Now, I want to add my factbox under the Attachment.

Here is my AL Code:

pageextension 50124 "Customer Card PageExt" extends "Customer Card"
{
    layout
    {
        addfirst(factboxes)
        {
            part(FDDDragAndDropFactbox; "Sharepoint_Files_Factbox")
            {
                ApplicationArea = All;
                SubPageLink = "Table ID" = const(18), "No." = field("No.");
            }
        }
    }
}

As far as I know, there is no way.
The Attachments tab only supports system factboxes, which only Microsoft can add.

On the other hand, if you add Document Attachment, Links, Notes, no matter what the name is, it will go to Attachments tab.

For exmaple,

The Attachments tab typically only supports system-generated factboxes that Microsoft provides, and there is no direct way for users or developers to add custom factboxes to this specific tab.
