Unable to setup HANA as secondary database connection to ECC

Hi there,

I am trying to follow the following blog to setup HANA as secondary database connection to ECC but encountered error when I try to create the connection in tcode DBACOCKPIT.

I am getting the following error message:

"Exception CX_DB6_SYS in class CL_DB6_SYS method SET_DBC_NAME line 29 / RC=Error in connection administration"

I did a quick debug and it seems like it class CL_HDB_DBCON is missing. According to the basis, everything is patched to the latest version. Any idea how I can fix this up?

Thanks,

TM
