Only a limited number of users can access certain parts of R:BASE at the same time. Be sure that all network users are aware of the limitations and plan ahead to avoid conflicts in accessing database and application files. A user should operate in single-user mode when performing any operation that modifies the structure of the database or using the PACK command.

The limitations to access for users are listed in the R:BASE Access Limitations Table.
