So does this mean that even if the tables are not visible in the ODBC wizard, as long as I know what table name to target in the script, I can still extract any data I need with a driver connection?Īlso, it seems that some measures would have to be aggregated in order to be extracted:Ĭould you please share from your experience regarding QV SAP Connector (SQL) vs. It seems that the solution would be knowing table names upfront in order to extract data. The main purpose would be a QV connection and data extraction from SAP S/4 Hana.įrom what I have read, the main convenient is that the source tables are automatically exposed once a connection with SAP connector is established, in comparison to a HDBODBC driver, where tables are not always visible. Execute the scripts in the source database.Would you know, in short, what are be the benefits of SAP Connector over HDBODBC?.

Finally, the driver should also show up as 'ODBC DataSources 32-bit' or 'ODBC DataSources 64-bit'. The driver is usually installed by running hdbsetup.exe. 64-bit Excel/Power BI Desktop, youll need the 64-bit ODBC driver (HDBODBC). The task will run and generate the scripts for creating the CDC artifacts in the following location and then stop: 32-bit Excel/Power BI Desktop, youll need the 32-bit ODBC driver (HDBODBC32). Once the task is defined, select any of the Metadata only options in the Advanced Run Options window, and then click OK.

Define the task as you would any other Replicate task, but when configuring the SAP HANA source endpoint, clear the Create CDC Artifacts check box in the Advanced tab.

When defining the SAP HANA source endpoint, make sure that the Create CDC Artifacts check box in the Advanced tab is selected (the default).

To create the CDC artifacts automatically (the default):

64-bit Excel/Power BI Desktop, you'll need the 64-bit ODBC driver (HDBODBC). The table will either be created in the schema of the user specified in the General tab of the SAP HANA endpoint settings, or in the schema specified in the endpoint settings' Advanced tab. 32-bit Excel/Power BI Desktop, you'll need the 32-bit ODBC driver (HDBODBC32). During the task, Replicate reads the changes from the attrep_cdc_log table and deletes the old data according to the cleanup settings (specified in the endpoint's Advanced tab).

The Replicate attrep_cdc_log table: When the Use log table option in the SAP HANA endpoint's Advanced tab is enabled, changes are copied from the attrep_cdc_changes table to the attrep_cdc_log table.

This may not be the actual number of UPDATEs performed on the source since UPDATEs are sometimes merged with INSERTs (depending on when the attrep_cdc_changes table was last scanned). The Replicate attrep_cdc_changes table: This table will contain changes captured by the triggers and will either be created in the schema of the user specified in the General tab of the SAP HANA endpoint settings, or in the schema specified in the endpoint settings' Advanced tab.Īs Replicate periodically scans the attrep_cdc_changes table for changes, the number of UPDATEs shown in the monitor's Change Processing tab reflects the number of UPDATEs found (in the attrep_cdc_changes table) at the time of scanning.

The triggers will be created in the source table schema. A separate trigger is required for each DML operation. Three triggers for each of the designated source tables: The triggers capture changes to the source tables (INSERTs, UPDATEs, and DELETEs) and write them to the Replicate attrep_cdc_changes table described below. Replicate requires the following artifacts to be created in the source database (either manually by the DBA or automatically by Replicate): The prerequisites for both of these methods are described below.

The driver name is HDBODBC.Īdd the following section to the odbcinst.ini file located in directory /etc:Ĭhanges can be captured from SAP HANA using either of the following methods:

Hdbodbc driver update install#

Linux: Install the SAP HANA ODBC 64-bit Driver 2.x for Linux on the Replicate Server machine.

Hdbodbc driver update windows#

Windows: Install the SAP HANA ODBC 64-bit Driver 2.x for Windows on the Replicate Server machine.

Open inbound port number 3xx15 to the SAP HANA server where xx is the instance number of the SAP HANA database that contains the source tables.įor example, the port for instance 90 would be 39015. Before SAP HANA can be used as a source endpoint in a replication task, the prerequisites described in this section must be met.
