Generate Cost Accounting Events (for AA) Versus Create Accounting SLA

We are doing Project Costing on Misc Trans (inv) and Labor (straight Time) in EBS 12.2.8.  We distribute Labor and Material Costs then Generate Cost Accounting Events to deploy Account default via Auto Accounting

then want to update some values with Sub Ledger Accounting (Create Accounting) Processes and review and send to GL.

Slight confusion as to the overall process because it appears after Cost Distribution and Generate Cost Accounting for Inventory (The Auto Accounting Processes), we ran the interface Streamline process to GL and the Accounting went to GL and was posted and then no eligible events when we ran the SLA Create Accounting Processes.
