## About managed views
<a name="about-managed-views"></a>

Managed views can be updated or deleted only by the service that created the managed view. An AWS service creates a managed view using [IAM forward access sessions (FAS)](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_forward_access_sessions.html) or a [service-linked role (SLR)](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_create-service-linked-role.html). 

Resource Explorer uses a [resource-based policy](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies_identity-vs-resource.html) to control access to the managed view. When an AWS service creates a managed view, Resource Explorer attaches the resource-based policy to the view. This policy allows the managing AWS service to use and delete the view and allows view's resource owners to list and retrieve details about the view. The following is an example resource-based policy attached to a managed view:

Managed views can only be deleted by the AWS service that manages them. Before the managing service can delete the view, you may need to perform service-specific tasks to remove a managed view from your account. 

Resource Explorer managed views use the AWS Systems Manager `AWSManagedViewForSSM` unified console resource, which allows Systems Manager to access resource information indexed by Resource Explorer for your organization. If you want to delete the managed view, you must disable the unified console in Systems Manager. For instructions, see [Disabling the Systems Manager unified console](https://docs.aws.amazon.com/systems-manager/latest/userguide/systems-manager-disable-integrated-console.html) in the *AWS Systems Manager User Guide*.
