Hi Ramón,
The "Details" link is provided as an alternative to "Abstract" when 1) no Galley link is available (e.g. there are no galleys, or the user doesn't have subscription access to a galley when subscriptions are enabled), and 2) an abstract has not been entered for the submission. Also look at the section's settings as Journal Manager to see if abstracts are enabled.
Regards,
Alec Smecher
