Root Cause
The initial exception that caused the request to fail, was:
com.sap.tc.webdynpro.services.exceptions.WDRuntimeException: Failed to resolve JCOClient name 'WD_RFC_METADATA_DEST'. No such JCO destination is defined in the SLD
at com.sap.tc.webdynpro.serverimpl.wdc.sl.JCOClientConnection.resolveConnectionParameter(JCOClientConnection.java:493)

Correction Hints
Retrieving a JCO destination with name 'WD_RFC_METADATA_DEST' from the System Landscape Directory (SLD) failed, as the destination could not be found in the SLD. The most probable reason for that is that the destination has not been maintained yet.
Use the preinstalled Web Dynpro Content Admin application to check/edit the destination. Use the Ping and Test functions of the Content Admin to verify that each destination is properly configured.
Additional information about the System Landscape Directory and the Web Dynpro Content Admin can be found in the SAP Developer Network (SDN) and in the Online Help for the SAP Web Application Server (installed with SAP NetWeaver Developer Studio and available online).
Note: the above hints are only a guess. They are automatically derived from the exception that occurred and therefore can't be guaranteed to address the original problem in all cases.
