Resolution:

For Design time, you will have to run/debug the application in Business Studio using debug level logging (Run/Debug Configuration--> click Advanced--> choosing logback_leveldebug.xml) . The Console tab in Studio will have the debug information logged.

For runtime deployment, you can change the debug level to "DEBUG" at the  root level in <BW_HOME>\bw\6.2\domains\<DOMAIN_NAME>\appnodes\<APPSPACE_NAME>\<APPNODE_NAME>\logback.xml as below:

++++++++++++

<!-- *=============================================================* -->

 <!-- * ROOT * -->

 <!-- *=============================================================* --> 

<root level="DEBUG">

 <appender-ref ref="FILE" />

 </root>

</configuration>

++++++++++++

The debug information will be captured in"bwappnode.log" under "<BW_HOME>\bw\6.2\domains\<DOMAIN_NAME>\appnodes\<APPSPACE_NAME>\<APPNODE_NAME>\log" .
