Similar like in the discussion "GW Data Model not available in SE80" in my System the Data Model option is missing in the dropdown. But my System is an SAP NW AS ABAP 7.40 SP2 with SAP_GWFND 740 0002 SAPK-74002INSAPGWFND SAP Gateway Foundation 7.40
Unfortunately the note 1647731 is only valid for 7.31.
Any ideas?
