Starting an SAP HANA Remote Subscription

For a DataSource with real-time replication, you can perform the delta initialization, that is, start the remote subscription, the initial data transfer, and the data replication.

  1. You are in the BW modeling tools in the DataSource on the Extraction tab page.

  2. For each remote subscription selected under Real-Time Replication, choose Manage. The administration screen of the remote subscription for the DataSource appears.

  3. To start the delta initialization, choose Execute.

  4. Specify whether you want the delta initialization to be started in dialog mode or in the background.

    If it is executed in the background, you can call the job log by choosing the Jobs pushbutton.

Executing the Delta Initialization Using a Process Chain

You can add the delta initialization to a process chain using the Start SAP HANA Remote Subscription process type. In this case, you specify in the process variant maintenance how the system is to behave in the event of a failed or repeated delta initialization for a remote subscription. If the remote subscription has a status that describes an intermediate state (for example, MAT_START_BEG_MARKER or AUTO_CORRECT_CHANGE_DATA), the system resets the remote subscription by default and deletes the data from the target table. If the remote subscription has an active status (APPLY_CHANGE_DATA), the system terminates the process with a success message by default.

For information about the remote subscription status, see Remote Subscription States for Data Provisioning in Administration Guide for SAP HANA Smart Data Integration and SAP HANA Smart Data Quality under http://help.sap.com/saphelp_hana_options_eim/helpdata/en/06/756fc260e548ed9f64c439b8649ced/frameset.htm.
