we recently upgraded HANA to SPS09 rev.92 (that serves as target & source) and start receiving this error in DS:
Data flow XY s not support UPDATE FROM with this version of SAP HANA. Disable the“ Use input keys ”loader option or update to a newer SAP HANA revision.
The target HANA table has option "Use input keys" set to "Yes" in DS. If I switch it to "No' than it works, but it was set to "Yes" probably from some reason.
The table in HANA has primary key.
I tested it on DS version 4.2 SP1 and also 4.2 SP4. With combination of Hana Client (ODBC) 1.00.68.384084 and also 1.09.18087.
