SAP BUSINESS CONNECTOR

SAP Business Connector (BC)

What is SAP Business Connector?

With the SAP Business Connector, SAP ERP systems can be connected to other SAP ERP and non-SAP environments. This enables the integration of different (even non-SAP) applications and technologies via open standards.

How does the SAP BC work?

The following functions are included in the Business Connector:

Calling methods from SAP applications: Via XML-based and generated Business Connector Services, BAPIs can be executed. The possible BAPIs can be accessed via SAP Interface Repository.

Calling methods from non-SAP applications: Third-party applications outside the SAP system can use the BAPIs via the SAP Business Connector and thus execute methods synchronously or asynchronously on the SAP server.

Using Remote Function Calls: The RFC server and client included in the SAP Business Connector can be used to access all SAP functionality via remote function calls (RFCs). The BC enables bidirectional communication with the SAP system for this purpose. For SAP-independent communication, the RFC format is first converted to HTML or XML and can then communicate with external systems that do not support the RFC protocol or other SAP data formats.

B2B integration: If the SAP server uses the BC, the infrastructure can be extended to enable B2B integration between business partners. The routing of SAP documents (IDoc) can be customized as desired. This makes it possible to send IDocs to other SAP systems or web addresses (e.g. via e-mail, HTTP or XML). It is also possible to exchange IDoc data via Application Link Enabling (ALE). IDocs can also be modified in the SAP Business Connector.

What features does the SAP Business Connector combine?

Thanks to the SAP Business Connector (BC), communication via interfaces between SAP and non-SAP systems is now possible. Functions can be accessed via the included library. The SAP Business Connector does not require licensing costs or large system resources. All functions used via BAPI and IDocs can be made available as secure XML-based services.

This allows different IT architectures or software solutions (such as the CPQ software calcIT) to be connected, processes to be optimized, and the efficiency of the entire supply chain to be increased.

What are possible application scenarios for the SAP Business Connector?

  • Exchange of data between SAP and non-SAP systems (e.g. via HTTP(S), FTP or e-mail)
  • Access to data sources on the Internet from the SAP system
  • Transmission of payroll tax returns and statements to the tax office (e.g. Elster)

How secure is the SAP Business Connector?

With the SAP Business Connector, two different concepts intertwine, thus ensuring security. External partners are integrated via reverse invoke. Network connections are made exclusively from the intranet (protected network). In addition, the Business Connector supports the Lightweight Directory Access Protocol (LDAP) and client certificates. Via LDAP, encrypted communication between server and client is possible using Transport Layer Security Protocol (TLS). Furthermore, secure authentication is performed under LDAP using the Simple Authentication and Security Layer (SASL).

SAP Business Connector (BC) from 31.12.2020 – migration necessary

According to SAP Note 1094412, support for the SAP Business Connector will end on 31 December 2020, which means that the use of SAP ERP or SAP HANA after 31 December, 2020 should be well thought out, since companies will need to take care of Business Connector migration in time. Alternatives may include local solutions as well as managed solutions (e.g. EDI). SAP itself offers SAP Process Integration (SAP PI) or SAP Process Orchestration (SAP PO), a newer middleware platform for connecting an SAP system with non-SAP systems. However, the use of this platform is subject to a fee.
