BUG #: 14016 (Plato7x)



SYMPTOMS
While a Microsoft Decision Support Objects (DSO) program can read the EstimatedRows property of the Aggregation class in the DSO library and assign a new value without receiving an error message, the value is not stored. This prevents OLAP Administrators from manually altering the EstimatedRows property in situations where they know the value generated by the partition analyzer algorithm is incorrect.



MORE INFORMATION
Analysis Services uses the EstimatedRows property to determine if an aggregation meets the size restrictions for inclusion in the aggregations for a partition or a cube. The EstimatedRows value is calculated based on the number of members at the various levels selected for the aggregation. This is the theoretical number of rows needed to store the aggregation. There are situations where the data storage for an aggregation may be considerably less than the theoretical number calculated because of data sparsity or dependencies between several dimensions. In these cases, valid aggregations that might help performance are not selected for a cube or a partition because the theoretical size of the aggregation exceeds the maximum permitted by the aggregation design algorithm.

In cases where the EstimatedRows for an aggregation are not in line with the actual rows required for an aggregation, the Analysis Services database administrator may want to change the EstimatedRows for an aggregation to more accurately reflect the actual aggregation sizes.



RESOLUTION
A supported fix is now available from Microsoft, but it is only intended to correct the problem described in this article. Only apply it to systems that are experiencing this specific problem. This fix may receive additional testing to further ensure product quality. Therefore, if you are not severely affected by this problem, Microsoft recommends that you wait for the next Microsoft SQL Server 2000 Analysis Services service pack that contains this hotfix.
