The experience reports were under the related information section of the Work Management topic. The subsystem configuration experience reports were covered in three sections:
The December 2016 update for Navigator for i included a number of enhancements; one of the most significant extends the work management tasks to include IBM i subsystem creation and configuration. This support is available for all current releases.
