You can reinitialize an individual analysis realm in the analysis server. This applies to the analysis realm configuration and the Data analytics data of all analysis realm tables of the analysis realm specified.
With the yes parameter, the analysis server is reinitialized regardless of whether the configuration or data of the analysis realm are consistent or not. That way you can eliminate potential inconsistencies.
If you use the auto argument, the analysis server is reinitialized only if required. That way you can eliminate potential inconsistencies.
With the default setting no (default) you prevent reinitializing completely.
Dimensions in associations between processes and tables are reinitialized only if you run ppmimport –reinitanalysisserver yes (see Reinitialize entire analysis server).
