On item level in a service contract, which service transactions are visible in a list?

In a service contract (scope item 3MO), the item-level transaction list shows:

Released service orders: Service orders (e.g., transaction type SRVO) linked to the contract item are visible once released, tracking service execution.

Completed service confirmations: Confirmations are linked to orders, not directly listed at the contract item level.

Released maintenance orders: Only relevant in advanced execution, not standard contract visibility.

Released customer service orders: Not a distinct transaction type in S/4HANA Service.This is part of the contract monitoring functionality."Released service orders are visible in the transaction list at the service contract item level." (SAP Help Portal, Service Contract Monitoring).
