Adapter for SAP supports the XML format for use with arbitrary RFC function modules. By using the new content-typeapplication/x-sap.busdoc, which is also used for BAPIs, you can easily post RFC function calls to Adapter for SAP.

These XML messages must provide a BizTalk XML envelope (for further information, see Using BizTalk Envelopes with Adapter for SAP). The call of the corresponding business document for the RFC function can be put in the body of the BizTalk message.

By using the BizTalk XML envelope and this content-type, you also enable the support for the new application-specific XML error documents, which are defined in the SAP Interface Repository.

You can post to the generated proxy services URL for the RFC function modules, or to the RFC routing gateway
