Hi,
as of 710 the ARFC2/JCO related destinations have to be maintained in the destinations, not in WD Content admin.

Caveat Confector!
ARFC1 destinations were created using the Web Dynpro Content Administrator tool. This tool is still available for compatibility reasons, but the destinations it creates arenot used by ARFC2 models!
Instead, you should use the “Destinations” tool found on the Configuration Management screen of the NetWeaver Administrator.
