Append and Merge between_Direct_HANA database and Import Azure failing

Hi Guys,

I am trying to create the report where two different databases are used as 

SAP HANA-Direct query

Azure analysis service-Import

As per requirement I need to calculate the difference between two columns belonging to two different databases.So I appended to create new table as other relationships were failing.

But while publishing the report it gives an error that credentials are different,whereas SAP HANA is configured correctly for gateway and individually its working fine.

Any help/suggestions would be appreciated

Thanks in advance
