These are the tabs for dossier documents within an activity.
They are at the top of an activity and are only visible if a document has been uploaded for you to use within the process.
A document can be flagged as relevant or as an ‘other document’. Whether a document is deemed relevant is determined by which activities are open for you. Relevant documents can contain material that you need for the activity.
You can view any document by clicking that row. You can also download them by clicking the icon.
