Logical system problem

Hi Everybody,

I am using nwds for creating a web dynpro for java application which call the bapi to get the flight details. When I deploy and run the application this error is coming :-

<b>'WD_FLIGHTLIST_RFC_METADATA_DEST ' not properly defined! Unable to create Metadata connection for Dictionary Provider. Either the logical System Name 'WD_FLIGHTLIST_RFC_METADATA_DEST ' has not been properly defined in the System Landscape Directory, or you are not using a MsgServerDestination (AppServerDestinations are not permitted for Metadata connections).</b>

Please help me out.

Thanks in advance,

regards,

Madhu.
