Context: I recently got a job as a Junior DBA at a local company. They ordered me to make maintenance plans on a database and after investigating I found that SQL Server should have options from administration to generate them, as long as I log in to the server with a user that has sysadmin permissions (according to Microsoft documentation).
The fact is that I have such permissions and still do not have access
Any related information is greatly appreciated.
You probably don't have an edition of SQL Server that can work with maintenance plans.
If you have a version that is not supported by Agent, you cannot create maintenance tasks.
