Match for Duplicate Data jobs search for exact duplicates to consider them matched.
The maximum number of exact duplicates is based on the base object columns defined in the Duplicate Match Threshold property in the Schema Manager for each base object.
The Match for Duplicate Data job does not display in the Batch Viewer when the duplicate match threshold is set to 1 and non-equal matches are enabled on the base object.
To match for duplicate data:
Execute the Match for Duplicate Data job right after the Load job is finished.
Once the Match for Duplicate Data job is complete, run the Automerge job to process the duplicates found by the Match for Duplicate Data job.
Once the Automerge job is complete, run the regular match and merge process (Match job and then Automerge job, or the Auto Match and Merge job).
