Load CUBE data to SQL table using Script task

Recently I faced an issue while working with SSAS 2008 cube. I was using a data flow task and inside that I have OLEDB source (The Analysis Services 9.0 OLE DB Provider (msolap90.dll)) for fetching data using MDX query. I was running this package in BIDS, its working fine. But as I was trying to run it with DTEXEC command, it’s throwing following error:


• ERROR message:

SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code: 0x80040E05. An OLE DB record is available. Source: "Microsoft OLE DB Provider for Analysis Services 2008." Hresult: 0x00000001 Description: "Error Code = 0x80040E05, External Code = 0x00000000:.".


Component "OLE DB Source" (2297) failed the pre-execute phase and returned error code 0xC0202009.

Environment:
SSIS package on SQL Server 2005. BIDS 2005
SSAS cube on SQL server 2008.


Solution:
I have tried many possible solutions but no success. Finally I wrote a script task code which is connecting to CUBE and dumping the cube data in flat file with comma delimited format. Later on I used this flat file to laod data in SQL table.

I would like to share this code, may this helps other.

Important: Please add the "Microsoft.AnalysisServices.AdomdClient.dll" dll to your reference.


Microsoft.AnalysisServices.AdomdClient.dll is available under the link below,http://www.microsoft.com/downloads/en/details.aspx?FamilyId=228DE03F-3B5A-428A-923F-58A033D316E1&displaylang=en
