SCSM 2012 Data Warehouse Cube Processing Keep Failing

I personally find it very annoying when you imported a management pack (MP) in your SCSM and the next day all Cube Processing job failed without reason.

Have been seeking high and low for fix this and finally with combine article from Technet and forums by hundreds miserable user same as myself, the cube processing can be fixed using below method

Firstly lets Disable Data Warehouse Cube Processing jobs via Power Shell (make sure to change to correct Program Files install directory for SCSM):

Import-Module '%ProgramFiles% \Microsoft System Center 2012\ServiceManager\Microsoft.EnterpriseManagement.Warehouse.Cmdlets.psd1'
Disable-SCDWJob "Process.SystemCenterConfigItemCube"
Disable-SCDWJob "Process.SystemCenterWorkItemsCube"
Disable-SCDWJob "ProGetcess.SystemCenterChangeAndActivityManagementCube"
Disable-SCDWJob "Process.SystemCenterServiceCatalogCube"
Disable-SCDWJob "Process.SystemCenterPowerManagementCube"
Disable-SCDWJob "Process.SystemCenterSoftwareUpdateCube"

Login to the server hosting the Analysis service and run the powershell script, just remember to change the$Server.Connect and the $DWASDB with the correct server (being the name of the SQL Server) and database name. It usually runs for 5-15 minutes. In my case, it took me about 45 minutes, so not to worry if the Powershell hung. When complete, you can verify by looking at the properties at one of the dimensions

[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.AnalysisServices")

$Server = New-Object Microsoft.AnalysisServices.Server
$Server.Connect("serverdw.blog.com")
$Databases = $Server.Databases
$DWASDB = $Databases["DWASDataBase"]
$Dimensions = New-Object Microsoft.AnalysisServices.Dimension
$Dimensions = $DWASDB.Dimensions

foreach ($Dimension in $Dimensions){$Dimension.Process("ProcessFull")}

Now you have to enable back all the cube processing job you have disabled earlier.

Enable-SCDWJob "Process.SystemCenterConfigItemCube"
Enable-SCDWJob "Process.SystemCenterWorkItemsCube"
Enable-SCDWJob "ProGetcess.SystemCenterChangeAndActivityManagementCube"
Enable-SCDWJob "Process.SystemCenterServiceCatalogCube"
Enable-SCDWJob "Process.SystemCenterPowerManagementCube"
Enable-SCDWJob "Process.SystemCenterSoftwareUpdateCube"

The final step to do is to process all the cubes

Notice that the cube processing finish without error.

hope this help out all other out there with SCSM 2012 Cube Processing issue.
