A company collects customer mobile numbers into AEP from multiple sources.

Merge policy is a feature that allows users to define how data from different sources should be merged into a single profile. Users can specify the priority of data sources and the rules for resolving conflicts. This way, the company can use the unreliable data source as a backupsource only when the other sources do not provide the mobile number. References: : Merge Policy Overview : Merge Policy UI
