A publish report data job is a system-generated job that updates the details of matched and merged records in reports and generates report data for these records.
When you enable merge history activity for reports, the publish report data job automatically runs to publish report data for existing records. Subsequently, the job runs each time an ingress, file import, or match and merge job runs. This ensures that the reports you generate reflect the updated source record details from these jobs.
After a publish report data job starts, you can monitor and view the job details on the My Jobs page.
When a publish report data job runs, the job first indexes records for report requests. After the records are indexed, the publish report data job updates the information of master records, such as details of source records and rules used to master the records, into the merge history activity of source records.
For more information about merge history activity reports, see Manage reports.
