Solution
As of 3.0A, SAP supports 2 variants of OLE automation:
1. ABAP/4 can be used as an OLE controller (OLE client), that means: every external application that is represented as an OLE automation server can be controlled with ABAP/4.
Documentation: HELP OLE in the ABAP/4 editor.
2. The SAP System also represents itself as an OLE automation server where all function modules that can be called remotely can be accessed from any OLE client.
Documentation: OLE automation server

The remaining OLE interfaces (Embedding, InPlaceActivation, Drag&Drop) and OCX are not yet supported.
