Increasingly, web applications expose information on simple Web pages. For example, catalogs used in procurement and selling applications are available over the internet. Users can access the information easily. But in some cases this is not enough. Hence, companies can use the SAP Business Connector to retrieve catalogue information from a suppliers website and integrate the information with internal applications – automatically and in real time.

SAP Business Connector provides the users with Web Transaction Facility, which is a data, recall facility on the SAP systems. This facility enables the users to select the required RFCs and BAPIs and create the SAP XML document that is required for selected functions during the preparation stage. These services are included in the interface service of the Web Transaction Package of SAP BC and comprise the following service functions.
Search Function
Create Template
Invoke RFC
Creating, searching and invoking RFC Function
The Search function searches the SAP systems for available RFCs and BAPIs. The input parameters for this function are:
- sapServerName – Symbolic name for the SAP server
- functionName – Name of the RFC or BAPI sought.
The return of this function is in XML document of the type that is defined for Web Transaction communication. It is a list of RFC’s or BAPI’s with some descriptive data including the RFCs found, associated group, application, host and brief description.
The Create Template returns either the SAP XML document for the call (XML element) call or the return value of the call (XML element value) for a given RFC or BAPI. The Input parameters for a Create Template are:
- sapServerName – Symbolic name of the SAP server
- functionName – Name of the RFC or BAPI
- call – Call or Return Document. (true/false)
Invoke RFC function as the name suggests performs the function of invoking specified RFC/ BAPI. It invokes the call by using an XML document with a MIME type application. And the result is returned in the form of a SAP XML document. The input parameters in this case are:
- sapServerName – Symbolic name of the SAP server
