The history button available on edit screens controls access to a pop up screen that shows the history of additions, updates and deletions to attachments. In addition, the screen shows a record of all users who have downloaded the attachment to their own computer.
The same ATTACHMENT_HISTORY LAYOUT is typically used throughout an installation, and can be defined in the global layout area only. Other Business Areas and Projects will automatically inherit it from there. Of course, different ATTACHMENT_HISTORY layouts may be defined in each Business Area and Project.
