The connector in Teiid is actually for SAP NW Gateway, SAP's OData server. The only way to access BAPI directly from JBoss is via the JCo Camel component. See https://access.redhat.com/documentation/en-US/Red_Hat_JBoss_Fuse/6.1/html/Apache_Camel_Component_Reference/files/SAP.htm…
IDoc support is also in the works for this component, but not available in Fuse 6.1.
We have talked about integrating this Camel component with DV, but are still in the discussion phase.
