Remarks

The NotifyTableChange command allows a client application to explicitly notify an Analysis Services instance that one or more tables contained in a data source have been changed. For proactive caching, this notification indicates that relational OLAP (ROLAP) objects based on those tables should be reviewed and updated.

This method of notification is best used for ROLAP objects based on views or named queries defined in a data source view for which changes can be hard to detect and track.

The Object element must refer to a data source in the Analysis Services database. If the Object element refers to an object other than a data source, an error occurs.
