Additional Hints
Within the SIW transaction, you can navigate from the displayed log
dialog to the erroneous mapping node. When you double-click the log
message, the system opens the corresponding detail screen and leaves the
log open. This enables you to correct the incorrect mapping entries
right away. To update the log messages, click the Mapping Check
pushbutton again.
