Hi Gregory,
Thanks for the response,
Current scenario at the client is, SAP BW data was loading into Cognos but they have replaced SAP BW with stand alone hana( not BW on Hana). In Hana a calucation view , similar to the logic of SAP BW cube is created and loaded with data.So the output of caluclation view in Hana should be loaded to Cognos TM1. They have cubes in cognos which has scripts and transformations to do further analysis.
As all the all the logic in TM1 is in place and users are comfortable in using Cognos, we don't have an option of chaning the whole scenario. Only option is load data from HANA to Cognos .
Thanks,
Ravi.
