G-Invoicing Budget Baseline accounting

Pre-G-Invoicing the Budget baseline was happening with Budget Baseline Form in Projects Core form.

The Accounting would be generated at the time of Submitting and Baselining the Budget from the Core Form.

In G-Invoicing how does the Accounting get generated for the Budget Baselining. The submit button in the core form is disabled. The Implementation guide says at the time of Order approval Budget is baselined and accounting is generated. There are no CCID setup's where is the accounting generated?

What do we need to configure to generate the Budget Baseline accounting. When does this accounting actually get generated in G-Invoicing
