Bug: #50001609 (SQL Hotfix)
Microsoft distributes Microsoft SQL Server 2005 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 2005 fix release.

SYMPTOMS

Consider the following scenario. In Microsoft SQL Server 2005 Analysis Services, you perform a writeback operation in a transaction. Then you roll back the transaction. When you query the data, you notice that SQL Server has not rolled back the writeback operation.

CAUSE

This issue occurs because SQL Server 2005 Analysis Services uses caches. A cache stores the results of calculations that occur when you perform the writeback operation. When you roll back the transaction, SQL Server does not roll back the cache. Therefore, when you query the data, SQL Server retrieves incorrect data from the cache.

RESOLUTION

The fix for this issue was first released in Cumulative Update 3. For more information about how to obtain this cumulative update package for SQL Server 2005 Service Pack 2, click the following article number to view the article in the Microsoft Knowledge Base:
939537 Cumulative update package 3 for SQL Server 2005 Service Pack 2
Note Because the builds are cumulative, each new fix release contains all the hotfixes and all the security fixes that were included with the previous SQL Server 2005 fix release. Microsoft recommends that you consider applying the most recent fix release that contains this hotfix.

937137 The SQL Server 2005 builds that were released after SQL Server 2005 Service Pack 2 was released
Microsoft SQL Server 2005 hotfixes are created for specific SQL Server service packs. You must apply a SQL Server 2005 Service Pack 2 hotfix to an installation of SQL Server 2005 Service Pack 2. By default, any hotfix that is provided in a SQL Server service pack is included in the next SQL Server service pack.

WORKAROUND

To work around this issue, clear the cache manually after you roll back the transaction. To do this, use the ClearCache command in the Multidimensional Expressions (XMLA) language. For example, run the following XMLA query to clear the cache for the AdventureWorks database:
<Batch xmlns="http://schemas.microsoft.com/analysisservices/2003/engine">
  <ClearCache>
    <Object>
      <DatabaseID>AdventureWorks DW</DatabaseID>
    </Object>
  </ClearCache>
</Batch>

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
