SPC automatically creates a default SQL Server data source for you called CIMPLICITY Logging - SPC. New SPC documents will use this data source by default. It is strongly recommended that you continue to use the SQL Server data source.
All the SPC documents in a CIMPLICITY project must log their data to the same SPC data source. You can share an SPC data source between projects, or you can create a data source for each project.
