Yes Michael. I have made sure that all the prerequisites are fulfilled.
1. SAP_HCM -> This is the SAP delivered schema for SAP HANA Live views EHP4, which contains HCM views. We have already done schema mapping for SAP HCM to SAPABAP1.
2. This is an integrated Landscape where all the tables are already present in SAPABAP1, hence no possibilties of any tables missing.
3. I am not sure why it is still going to find SAP_HCM schema when I schema mapping is already done 
ColumnTable SAP_HCM:PA0000
ColumnTable SAP_HCM:PA0008
ColumnTable SAP_HCM:PA0002
ColumnTable SAP_HCM:T77S0
Schema mapping is already done as shown below.
4. According to your document, sufficient authorizations are also given to my userID as shown below.
The context of the matter is I am able to execute the HANA Live view but not getting any data. Hence, I need to go and check node by node to understand why the data is not reaching sematics layer of calc view. This is where I am failing. Please suggest.
Thanks,
Gaurav
