The Clever Device Log Table has been added to the list of allowed Tables which can be used with the standard Business Central Retention Policies functionality.
A Retention Policy record can be created and is used to define how frequently you would like Business Central to delete outdated data in Tables that contain log entries and archived records. More information can be found here Clean Up Data with Retention Policies
You can run the Retention Policy Wizard from the Clever Device Framework Setup Page in order to assist with creation of the Retention Policies.
