After the CAS server is restarted, you might see
errors saying Could not get BY groups. Some of the project
tables could have trouble reloading. The attributes in the Filters pane might not load correctly. In Interactive Modeling, the model selection
list table and the time seriesan aggregation of transactional data into specified time intervals and sorted according
to unique combinations of the default attributes (BY variables) in the right pane might have problems loading.
The data and properties of the project are in inconsistent state and need to be refreshed.
If you discover any problems while working in a project, exit the project and then reopen it. This could be caused by the CAS server stopping and restarting. Restarting the project resets the state of the data and properties.
