If a workflow instance includes a Mapping task, the Data Integration Service generates a separate log file for the mapping. The mapping log file includes any errors encountered during the mapping run and load summary and transformation statistics.

You can view the workflow and mapping logs from the Monitor tab.

When you recover an interrupted workflow instance, the Data Integration Service appends log events to the current workflow log. When the recovered workflow instance includes a Mapping task that is restarted, the Data Integration Service creates a mapping log.

If the workflow runs on a grid, the recovery of the workflow instance might run on a different node than the original workflow instance run. If the recovery runs on a different node and the log directory is not in a shared location, the Data Integration Service creates a log file with the same name on the current node.
