A match candidate group is a set of records in your input data that have something in common. For example, a match candidate group might consist of records containing the same postal code, city, or window key.
When you create a match candidate group you filter the records in your data, creating a subset of records that will be compared with each other in the window match. The original data is still available and is displayed on the Input Data tab; the candidate group will be used to perform the match and is displayed on the Match Candidates tab.
