Revoking Interface Assignments 
You can revoke an interface assignment to an action.
To revoke an interface assignment, select the table row with the interface and choose Delete Selected Rows.
Caution
Ensure that the interface is no longer part of a connection in a Process Integration scenario. In such a case, revoking the interface assignment would mean that the Process Integration scenario is inconsistent.
For more information, see the related messafe under Messages and Troubleshooting.
If the interface assignment to the action is revoked, the interface disappears from the table Inbound Interfaces or Outbound Interfaces of the Action Editor.
