Batch run static class method

Hi all,

Running AX 2012 R3 CU9. I may be using the wrong terminology for this request - it appears batch jobs within Dynamics always use SQL queries?

I have a custom static class method which I currently run by putting it inside an empty Job and then running the job. I'd like to be able to have this method be run automatically at midnight if it is possible

How could I go about doing this?

Thanks very much in advance

Luke
