  • As a backup, take screen shots of the current settings of [Provisioning> Configure Reportable Custom Fields], for all 3 template types (JRDM, CPT, CDM).
  • Remove all the mapped fields. Start from a blank slate. Save, and Synchronize.
  • Replicate the issue at your end followig the steps in the section above. You should no longer be able to see the error.
  • Go back to Provisioning> Configure Reportable Custom Fields and manually rebuild the custom reportable fields in the 3 templates, verifying that the settings are correct for all fields on all templates (Job Req, Candidate Profile, Application)
