The execution plan of SSAS processing engine triggers a sequence of processing tasks based on the object’s current processed state and its dependencies with other objects. This is what happens when the SSAS cube is processed from SQL Server Management Studio (SSMS). It is possible to replicate this execution plan close enough in an SSIS package so that the cube is always processed and refreshed with latest data.

SSAS: Troubleshooting this exception – “An unexpected error occurred (file ‘mdinfo.cpp’, line nnnn, function ‘MDInfo::Init’)”
What’s this exception?
[Analysis Services Execute DDL Task] Error: Internal error: An unexpected error occurred (file ‘mdinfo.cpp’, line nnnn, function ‘MDInfo::Init’).
My guess is that it’s most likely an unhandled exception from the product. I recently encountered this exception while processing index of a particular SSAS Cube using SSIS Analysis Services Processing Task. The cube did get processed in a previous step and only the process index step failed, the cube was still available for browsing minus the indexes.
