SQL Server: удалить Maintenance Plan

Почему-то просто через Management Studio удаление не срабатывало.

Нашлась вот такая последовательность действий:

1. Select the ID with the select statement
select * from sysmaintplan_plans

2. Replace with the selected ID and run the delete statements
delete from sysmaintplan_log where plan_id = ''

delete from sysmaintplan_subplans where plan_id = ''

delete from sysmaintplan_plans where id = ''

3. Delete the SQL Server Jobs with the Management Studio
