Data profiling

Dataedo supports profiling tables imported from SAP HANA.

During the profiling process SAP HANA's special dates are treated as regular values, not NULLs. Some database explorers (eg. DBeaver) can display NULL in a place of special date because of limitations of the JDBC driver. You can read more here.
