Budget: How to check if the set up is working

Once we completed set up budget using "Final by Account" cycle, how I can check if the set up is working in the test environment.

For example, for the account 4-700950-006 (Office expenses), we have set up $1200. And it automatically spread over 12 period $100.

Now, how I can check if this is working ? Should I create purchase order? or payment or ... ?
