Purging Match Decision Data

Match Decision data is not purged along with the rest of the results data. Match Decisions are preserved as part of the audit trail which documents the way in which the output of matching was handled.

If it is necessary to delete Match Decision data, for example, during the development process, the following method should be used:

  1. Open the relevant Match processor.
  2. Click Delete Manual Decisions.
  3. Click OK to permanently delete all the Match Decision data, or Cancel to return to the main screen.

Note:

The Match Decisions purge takes place immediately. However, it will not be visible in the Match Results until the Match process is re-run. This final stage of the process updates the relationships to reflect the fact that there are no longer any decisions stored against them.
