About the SAP HANA Database catalog source

You can use the SAP HANA Database catalog source to extract metadata from an SAP HANA Database source system.
SAP HANA Database is a multi-model database system that stores data in its memory and performs high-speed processing and analytics of data.

Extracted metadata

You can extract specific metadata from an SAP HANA Database source system with an SAP HANA Database catalog source.
Metadata Command Center extracts the following objects from an SAP HANA Database source system:

Data profiling for SAP HANA Database objects

Configure data profiling to run profiles on the metadata extracted from an SAP HANA Database source system. You can view the profiling statistics in Data Governance and Catalog.
You can run data profiles on the following SAP HANA Database objects:
The data profiling task runs profiles on the following data types:

Decimal (precision, scale) or Dec (p, s)
Precision 1 to 34
Decimal
Precision 1 to 28, scale 0 to 28
For transformations that support precision up to 38 digits, the precision is 1 to 38 digits, and the scale is 0 to 38.
For transformations that support precision up to 28 digits, the precision is 1 to 28 digits, and the scale is 0 to 28.
If you specify the precision greater than the maximum number of digits, the Secure Agent converts decimal values to double in high precision mode.
