We have many filtered data extensions created in Marketing Cloud. I need confirmation on retention period for FDE's for data protection rules.
Are there any rules applied on retention for filtered data extensions?
Rules are based on your data retention policy. Whether it's 6 months or indefinite. However, if you have a filter and a DE that either has an ETL process or updates, then refresh your FDE and whether it is indefinite or 6-months, it won't go away.
Required, but never shown
