fdgolf,
Crew list is usually a crew dec or gen dec (decleration) which used to list the crew members with their details- passport numbers, date of birth etc. Thanks to the EU it's no longer required for internal EU flights but unfortunately is still required almost everywhere else for customs/immigration/quarantine - CIQ - reasons.
However, a company might have an internal requirement for such a list, especially for a large aircraft with a big number of crew but that wouldn't be a legal requirement.
