I am implementing a periodic snapshot for inventory levels. When implementing surrogate keys, should these be applied to every snapshot take (eg. the entire dataset is updated with the current SK) or just the current day's snapshot?

A bit more context would be useful. What do you use the snapshots for?
If you haven't even tried to resolve your issue, please don't expect the hard-working volunteers here to waste their time providing links to answers which you could easily have found yourself.
