## Deleting DMs in scope of Schedules

When a DM is being used in an open Schedule it cannot be expired. You will get an error messages as shown below.

This is because when an RBI Component-DM is put in the scope of a Schedule and Approved, it becomes part of the Schedule history.

The only way to delete the DM from the CL is to:

- Put the Schedule (that has the RBI Component-DM in scope) back into Draft.
- Remove the Component from the Schedule Scope.
- Then remove the assigned DM from the Component, i.e., expire the RBI Analysis:
  - Click **New Analysis**.
  - Uncheck the box next to the DM that is to be removed.
  - Click **Save**.

When there are not RBI Analyses on the DM, the [DM can be deleted in the CL](/v414/docs/deleting-dms-barriers-notes#deleting-barriers-and-dms-not-yet-in-scope-of-a-schedule). Note: Even after removing the RBI Component from the Schedule scope, it is left as part of the history, which will prevent the deletion of the Component. Only the DM can be deleted.
