Hi All,
I am working on a MS BI project. The details and the issue are as follows:
Issue: Everything works fine as usual when the cube is processed and reports are deployed. After some days, the reports start returning incorrect data. I cannot say incorrect data in specific but the base measures become null and if we take the original query from SSRS, run in MDX query window or browse it from the cube for the same selection criteria, the base measures show null while calculated memebers in cube sometimes return data/sometimes not.
And if we remove any of the attribute from the select clause or remove/add any thing into subcube of mdx query gives correct results.
Strange thing here is keeping everything same, clear the cube cache or reprocessing the cube resolves the issue.
Details:
The SQL server version: (Microsoft SQL Server 2008 R2 (SP2) - 10.50.4000.0 (X64) Jun 28 2012 08:36:30 Copyright (c) Microsoft Corporation Enterprise Edition (64-bit) on Windows NT 6.1 <X64> (Build 7601: Service Pack 1) )
Cube: The cube contains around 45 dimensions All of the dimensions are directly related to the fact except 4 dimensions.
Among 4 dimensions(parentchild dimension1, parent child dimension2, Dimension3 and Dimension4) above , 2 are parent child dimensions. Parent Child dimension 1 is related to the fact through many to many and parent child dimension 2 is related to the fact through reference relationship. Dimension3 is related to fact through many to many. Dimension4 related to the fact through cascading many to many.
And cube is pure MOLAP.
SSRS : SSRS reports fetch the data from cube. In MDX, we are using subcube to limit the data and slice the data. And theparentchild dimension2, Dimension3 mentioned above is always a part of the subcube.
Your help would be greatly appreciated.
Thanks and Regards,
Dinesh
