How can I download log files for the extract run processes?

Use the View Extract Results task. Search for the extract and click the extract instance name link in the search results, for which you want to view the extract result details. In the extract details page, the Instance Details tab lists the extract run processes. You can download the process log files to troubleshoot the extract run.

You can review the log files to identify the records that did not retrieve the expected data and to identify time consuming processes.
