True or False: A different prefix for a custodian on the processing data source overrides the profile prefix.

The assertion is true because in Relativity, when defining custodians for processed data sources, a different prefix set for a custodian can indeed take precedence over the profile prefix. This means that when a custodian's specific prefix is assigned, it effectively overrides the general prefix established in their user profile.

In scenarios where prefixes are utilized, they serve to create unique identifiers for custodians, enhancing data management and organization. If an individual custodian has a designated prefix that differs from the one set in the profile, that custodian's specific prefix will be applied to their data, ensuring clarity and consistency in managing the custodians' information throughout the processing workflow.

Therefore, when dealing with data extraction and processing, understanding the hierarchy and interaction between profile settings and custodian-specific configurations is crucial for accurate data handling.
