Check your SAS contract what the measurement is.
Named users (often done), Number of pc's it is installed on, Number of users/machines that could get access to it.
Servers and Solutions can be negotiated to some others options.
Stand alone installations are only possible to capture when they are being scanned (manually/automatically).
The setinit in SAS in confused as a license (the license is your contract), the setinit is only a technical approach to overcome technical abuse (hacked copies)
The SID is a reflection of your contract but also not your license the SID is used for installation purposes, using the SDW.
Within professional organizations there is a closed desktop approach. This implies that the SDW is almost useless and only causing more complications.
This approach is because of common ICT policies set by regulations where you need to underpin only approved software may be used.
In that professional approach there is often some flexible hardware approach with roaming profiles. All depends with that on your registration which packages (SAS needed to be repackged) to which persons (named users, auditability) is allowed. There you have your connection to licenses on software.
