In the above example, the access is from ABAP/4 programs to OLE objects made available on the<br />

desktop by application programs.<br />

Special ABAP/4 OLE statements use the SAPGUI to make RFCs on the desktop side. The SAPGUI<br />

software then executes OLE-specific calls from the desktop.<br />

In this way, you can use an ABAP/4 program to control all desktop application objects made available<br />

via an OLE 2.0 Automation server program (e.g. EXCEL, MS Word, ...).
