Inside Customer Insights – Data
Two records. One person—or two?
Matching rules connect customer records across tables in Customer Insights – Data. This example shows the fields and precision used to define a condition. We work with your data owners to test which identifiers provide reliable matches and where ambiguity needs attention.

Microsoft documentation example: the Customer Insights – Data matching-rule editor. The fields and precision must be configured and validated for your own source data.
