In some cases, after upgrading a NAV database from Version 5 or earlier to Version 5 SP1 or later, the conversion may leave unnecessary tables named CRONUS$37$4 or similar in the database. These tables do not cause any problems, but they can contain a lot of data, and they are not needed.
Before version 5 SP1, NAV maintained SIFT totals in SIFT tables. Since version 5 SP1, this has been changed to maintain the totals in Indexed Views. So conversion of a database from a previous version to version 5 SP1 or later, will remove the old SIFT tables and generate new Indexed views instead. Generation of the new Indexed views happens without problems, but in some cases, not all SIFT tables will get deleted. So in this case, the database will still have tables with a naming convention like this:
These tables can be safely deleted from the SQL Server
