Using Non-SAP Adapters
Adapters enable SAP NetWeaver to communicate with a variety of different application components and systems. Adapters also enable B2B communication using industry-specific standards such as RosettaNet or CIDX.
SAP does not actually provide all adapters as such, but has a resale agreement with various business partners that make the adapters for systems and industry standards available. SAP currently has agreements with iWay and Seeburger.
These third-party adapters are sold and shipped by SAP.

For more information about these adapters, see SAP Developer Network (SDN) at https://www.sdn.sap.com/irj/sdn → SOA Middleware → Service Bus-Based Integration. In the Knowledge Center on the Service Bus-Based Integration page choose Connectivity.
For detailed information about each of the adapters, refer to the documentation shipped with the adapter software.
