Replicate SAP Data to Multiple Databases
Replicate SAP data to disparate databases with a single configuration.
Always-on applications rely on automatic failover capabilities and real-time access to data. CData Sync for SAP 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 or any machine running Java.
You can use Sync's command-line interface (CLI) to easily control almost all aspects of the replication. You can use the CLI to replicate SAP data to one or many databases without any need to change your configuration.
About SAP Data Integration
CData provides the easiest way to access and integrate live data from SAP. Customers use CData connectivity to:
- Access every edition of SAP, including SAP R/3, SAP NetWeaver, SAP ERP / ECC 6.0, and SAP S/4 HANA on premises data that is exposed by the RFC.
- Perform actions like sending IDoc or IDoc XML files to the server and creating schemas for functions or queries through SQL stored procedures.
-
Connect optimally depending on where a customer's SAP instance is hosted.
- Customers using SAP S/4HANA cloud public edition will use SAP NetWeaver Gateway connectivity
- Customers using SAP S/4HANA private edition will use either SAP ERP or SAP NetWeaver Gateway connectivity.
While most users leverage our tools to replicate SAP data to databases or data warehouses, many also integrate live SAP data with analytics tools such as Tableau, Power BI, and Excel.
Getting Started
Connect to SAP Data
You can save connection strings and other settings like email notifications in XML configuration files.
The following example shows how to replicate to SQLite.
Windows
<?xml version="1.0" encoding="UTF-8" ?>
<CDataSync><DatabaseType>SQLite</DatabaseType>
<DatabaseProvider>System.Data.SQLite</DatabaseProvider>
<ConnectionString>Host=sap.mydomain.com;User=EXT90033;Password=xxx;Client=800;System Number=09;ConnectionType=Classic;Location=C:/mysapschemafolder;</ConnectionString>
<ReplicateAll>False</ReplicateAll>
<NotificationUserName></NotificationUserName>
<DatabaseConnectionString>Data Source=C:\my.db</DatabaseConnectionString>
<TaskSchedulerStartTime>09:51</TaskSchedulerStartTime>
<TaskSchedulerInterval>Never</TaskSchedulerInterval>
</CDataSync>
Java
<?xml version="1.0" encoding="UTF-8" ?>
<CDataSync><DatabaseType>SQLite</DatabaseType><DatabaseProvider>org.sqlite.JDBC</DatabaseProvider>
<ConnectionString>Host=sap.mydomain.com;User=EXT90033;Password=xxx;Client=800;System Number=09;ConnectionType=Classic;Location=C:/mysapschemafolder;</ConnectionString>
<ReplicateAll>False</ReplicateAll>
<NotificationUserName></NotificationUserName>
<DatabaseConnectionString>Data Source=C:\my.db</DatabaseConnectionString>
</CDataSync>
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.
Configure Replication Queries
Sync enables you to control replication with standard SQL. 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. The statement below caches and incrementally updates a table of SAP data:
REPLICATE MARA;
You can specify a file containing the replication queries. This enables you to use the same replication queries to replicate to several databases.
Run Sync
After you have configured the connection strings and replication queries, you can run Sync with the following command-line options:
Windows
SAPERPSync.exe -g MySQLiteConfig.xml -f SAPERPSync.sql
Java
java -Xbootclasspath/p:c:\sqlitejdbc.jar -jar SAPERPSync.jar -g MySQLiteConfig.xml -f SAPERPSync.sql
