Bug #: 14249 (Plato7x)
NoticeMicrosoft distributes Microsoft SQL Server 2000 fixes as one downloadable file. Because the fixes are cumulative, each new release contains all the hotfixes and all the security fixes that were included with the previous SQL Server 2000 fix release.
When a user who is a member of a security role that has restricted access to one or more members of the Measures dimension queries a cube in SQL Server 2000 Analysis Services, they may receive zero values for measures that they have access to. This behavior may occur even though the actual values for the measures are not zero in the source cube.
Service pack informationTo resolve this problem, obtain the latest service pack for Microsoft SQL Server 2000. For more information, click the following article number to view the article in the Microsoft Knowledge Base:

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section. This problem was first corrected in Microsoft SQL Server 2000 Service Pack 4.
This hotfix includes a fix that addresses a problem that causes the corruption of dimensions when a Lazy Aggregation processing thread is executed after it processes dimensions that are used in virtual dimensions.
Because of that fix, if you incrementally process a virtual dimension, a lazy aggregation processing thread executes. While the lazy aggregation thread executes, the aggregations for that dimension are deleted from each partition. The lazy aggregation thread executes as a low-priority background thread and rebuilds the aggregations for the dimension in each partition.
While the lazy aggregation thread executes to rebuild the aggregations, multidimensional expressions (MDX) query execution may be significantly slower. The degradation in query performance occurs because of the lack of aggregations. The lack of aggregations causes the server to read values from the leaf level of each partition. After the lazy aggregation thread finishes rebuilding the aggregations for each partition, you will no longer see the degradation in query performance.
The query performance degradation during lazy aggregation may be unacceptable in certain situations, such as in high-demand cubes in enterprise applications. If applying this hotfix causes unacceptable query performance degradation, we recommend that you consider the following alternatives during lazy aggregation:
