SAP NetWeaver as Source
Capture
Fivetran HVR allows you to Capture changes from SAP NetWeaver using HVR's AppConnect. This section describes the configuration requirements for capturing changes from SAP NetWeaver location. For the list of supported SAP NetWeaver versions from which HVR can capture changes, see Capture changes from location in Capabilities.
HVR supports capturing changes from SAP NetWeaver only when the underlying database is either Oracle or SAP HANA. The requirements for capturing from NetWeaver is classified based on the underlying database:
SAP columns are non-nullable by default. They will be described as nullable in the hub's repository and thus as nullable in the target. This is valid for the non-key columns. Key columns will remain non-nullable.
SAP Data Types Conversion
Since v6.1.0/7
This option enables conversion/mapping of SAP specific data types (available in SAP dictionary meta-data) in source location to corresponding data type in the target location. The SAP specific data type will be localized with the source DB's data type and then mapped to HVR's Repository data type. For example, if you have an SAP system with NetWeaver driver, the DATS
data type will be mapped to HVR Repository type nvarchar
/ date
.
This feature is supported for the following SAP specific data types:
- DATS
If the SAP Data Types Conversion option is NOT selected, SAP specific data types are mapped to various other HVR Repositry data types. For more information, see Data Type Mapping for SAP NetWeaver (or SAP dictionary).
If the SAP Data Types Conversion option is selected during location creation, HVR will automatically define action TableProperties with parameters CoerceErrorPolicy and CoerceErrorType.
While creating an SAP NetWeaver location, the SAP Data Types Conversion option is selected/enabled by default. To enable SAP data type conversion for an existing location, select the SAP Data Types Conversion option by editing the location's source and target properties and then manually define action TableProperties with parameters CoerceErrorPolicy and CoerceErrorType.
Compare and Refresh from Oracle and HANA
HVR allows you to perform only Compare and Refresh from SAP NetWeaver (without using Capture). Any specific database (Oracle or HANA) grants are not required for performing only Compare and Refresh from NetWeaver on Oracle or HANA.
