The Build Match Group (BMG) process removes redundant matching in advance of the consolidate process. For example, suppose a base object had the following match pairs:

After running the match process and creating build match groups, and before the running consolidation process, you might see the following records:

In this example, there was no explicit rule that matched record 4 to record 1. Instead, the match was made indirectly due to the behavior of other matches (record 1 matched to 2, 2 matched to 3, and 3 matched to 4). An indirect matching is also known as a

transitive match
