The changes in the hotfix will resolve the issue by having the file attachment when we are making changes on invoice.
In fix new button for attachments at the header level and left the system defined button as is. So if the user clicks the header attachment button, it will always open the attachments window in the context of the header and the line attachment button will always open the attachments window in the context of the selected line. The system defined attachment button will still be based off of the currently selected data source (default functionality)
