We have 3 tables under this user account and are wondering if they are necessary?
Who is the owner of the tables. "SDE"?
Geodatabase
DBSFWUSER
I am not sure that those tables are part of system tables. Without more context and system information it is difficult to give you a good response.
If you look in the SDE.table_registry table do you see any tables with the owner "DBSFWUSER"?
