Entering Bank Charges in Oracle

We are implementing Cash Management on 12.1.3 for Bank Statement reconciliation.

The bank statement will have some bank charges. How can they be entered into oracle during manual and automatic reconciliation?

My understanding is that for manual recon, someone has to manually enter the bank charges into oracle. But i am not aware where and how.

For Automatic reconciliation, my understanding is that creating the bank codes for bank charges will create them in oracle. But again, I am not aware where and how.

I have been trying to find answer for this in the knowledge base and community but was unsuccessful.
