Hierarchies in HANA SP10

We are on HANA VERSION 102, we want to roll up the data based on cost element hierarchy.

I followed blog

http://scn.sap.com/community/hana-in-memory/blog/2015/07/09/new-hierarchy-sql-enablement-with-calculation-views-in-sap-hana-10-sps-10

1) Created a Calculation view (Dimension) for cost element with hierarchy.See attachment CE_HIER.png

2) Used the cost element calculation view in the STAR JOIN and joined with the fact table as mentioned in the blog.See attachment FACT_HIER.png

When i query the calculation view it does not look like rolling up the value to the root nodes.

Can you please check if i'm doing anything wrong? or is there a different procedure to work with hierarchies?

Thanks
