Replicate SAP Data to Multiple Databases

Always-on applications rely on automatic failover capabilities and real-time access to data. CData Sync integrates live SAP data into your mirrored databases, always-on cloud databases, and other databases such as your reporting server: Automatically synchronize with remote SAP data from Windows.

Configure Replication Destinations

Using CData Sync, you can replicate SAP data to any number of databases, both cloud-based and on-premises. To add a replication destination, navigate to the Connections tab.

For each destination database:

1. Click Add Connection.
2. Select a destination. In this article, we use SQLite.
3. Enter the necessary connection properties. To replicate SAP to a SQLite database, enter a file path in the Data Source box.
4. Click Test Connection to ensure that the connection is configured properly.
5. Click Save Changes.

Configure the SAP Connection

You can configure a connection to SAP from the Connections tab. To add a connection to your SAP account, navigate to the Connections tab.

1. Click Add Connection.
2. Select a source (SAP).
3. Configure the connection properties.
   
   

   The Java edition supports connecting to an SAP system using the JCo .jar file. See the "Getting Started" chapter in the help documentation for information on using the Jco JAR file.

   The Windows edition supports connecting to SAP systems using either the librfc32.dll, the librfc32u.dll, NetWeaver, or Web Services (SOAP). Set the ConnectionType connection property to CLASSIC (librfc32.dll), CLASSIC_UNICODE (librfc32u.dll), NETWEAVER, or SOAP.

   Note: We do not distribute the librfc32.dll or other SAP assemblies. You must find them from your SAP installation and install them on your machine.

   All versions of Sync support connecting to an SAP system using Web services (SOAP). If you are using the SOAP interface you must enable SOAP access to your SAP system and set the Client, RFCUrl, SystemNumber, User, and Password properties, under the Authentication section. Additionally, set the ConnectionType to SOAP.

   See this guide on obtaining the connection properties needed to connect to any SAP system.

4. Click Connect to ensure that the connection is configured properly.
5. Click Save Changes.

Configure Replication Queries

CData Sync enables you to control replication with a point-and-click interface and with SQL queries. For each replication you wish to configure, navigate to the Jobs tab and click Add Job. Select the Source and Destination for your replication.

Replicate Entire Tables

To replicate an entire table, click Add Tables in the Tables section, choose the table(s) you wish to replicate, and click Add Selected Tables.

Customize Your Replication

You can use a SQL query to customize your replication. The REPLICATE statement is a high-level command that caches and maintains a table in your database. You can define any SELECT query supported by the SAP API. To customize your replication, click Add Custom Query in the Tables section and define the Query Statement.

The statement below caches and incrementally updates a table of SAP data:

REPLICATE MARA;

You can specify a file containing the replication queries you want to use to update a particular database. Separate replication statements with semicolons. The following options are useful if you are replicating multiple SAP accounts into the same database:

• Use a different table prefix in the REPLICATE SELECT statement:

  REPLICATE PROD_MARA SELECT * FROM MARA;

• Alternatively, use a different schema:

  REPLICATE PROD.MARA SELECT * FROM MARA;

Schedule Your Replication

In the Schedule section, you can schedule a job to run automatically, configuring the job to run after specified intervals ranging from once every 10 minutes to once every month.

Once you have configured the replication job, click Save Changes. You can configure any number of jobs to manage the replication of your SAP data to disparate on-premises, cloud-based, and other databases.
