Which elements are removed from profiles and permission sets when a Custom Object is deleted?

When a Custom Object is deleted, dependencies are the elements that are removed from profiles and permission sets. This is because when a custom object is deleted, all associated metadata and relationships within the Salesforce environment, including any dependencies that reference that object, are also removed.

Dependencies refer to the associations that exist between the custom object and other components in Salesforce, such as fields, validation rules, and relationships with other objects. By removing these dependencies, Salesforce ensures that there is no lingering reference to an object that no longer exists, thus maintaining data integrity and preventing errors in the system.

Understanding that dependencies are automatically cleaned up during the deletion process helps maintain a streamlined and effective data model, ensuring that the environment remains organized and functional without orphaned references or broken associations.
