2. Identify applicable internal interest rates and fee schedules
3. Calculate interest income, interest expense, and transaction fees
4. Validate computed amounts against internal banking agreements
5. Generate journal entries for the calculated interest and fees
6. Post journal entries to the general ledger

Outcome: Interest and fee amounts are accurately computed, validated, and recorded as journal entries in the general ledger.
