This import bridge uses the SAP Java Connector (JCo) API libraries to connect to the SAP system and retrieve metadata. Ensure that the SAP JCo libraries are installed and accessible on the machine where the import bridge is executed.
The SAP JCo API communicates with the SAP server over the network using the following ports:
- Dispatcher port:
32NN— Used by SAP GUI for Windows and Java - Gateway port:
33NN— Used for CPIC and RFC communications - SNC-secured Gateway port:
48NN— Used for encrypted CPIC and RFC communications
In these port numbers, NN represents the SAP instance number
(00–99). Verify that firewall rules allow
communication through the required ports.
Before using this import bridge, configure the SAP ECC server by deploying the required ABAP RFC function module. An SAP user account with ABAP development permissions is required to create and deploy the RFC function module on the SAP server.
The RFC function module enables the import bridge to retrieve metadata from the SAP
system. Additional deployment instructions are available in the following directory:
<InstallDir>/conf/MIRModelBridgeTemplate/SapR3/
The SAP user account used by the import bridge must have sufficient permissions to connect to the SAP server and execute the following RFC function modules:
STFC_CONNECTION— Verifies connectivityRFC_SYSTEM_INFO— Retrieves system informationOCS_GET_INSTALLED_COMPS— Retrieves software version informationZ_MITI_DOWNLOAD— Performs the primary metadata extraction
The SAP JCo libraries may also invoke additional RFC function modules, such as:
RFC_PINGRFC_METADATA_GET
