It is very long winded to come from modules to underlying infos:
asset/cotract/contract to the underlying document-attachements:
First look in asset/contract/contract for the contract name and keep in mind,
then look in contract/misc/document for the associated document and keep in mind,
and then look in document/attachment to see the wanted document.
The linked items icon opens a window allowing users
to see all records somehow related to the current record being viewed.
To work efficient with the app there have to be Linked Items !
