DQM Match rules return Supplier parties in Searh result

Hi

We have been using DQM match rules to identify duplicates before creating customer in oracle from an external interface. The DQM rules score and match existing parties and update matched customer records.

But after the upgrade to R12.1.3 the DQM match rules return only the Supplier parties that were migrated as part of the upgrade. This is causing more errors and duplicates as the search does not return "Non- Supplier' parties

Any Clues / Suggestions will be helpful

Thanks
