# Service Termination / Disconnection & Data Retention

## Purpose

 Termination is the permanent lifecycle closure of a service/subscriber relationship. Termination must ensure charging is closed correctly, AAA access is revoked, and records are retained according to policy.

## Pre-termination Checks

- Confirm customer/account ownership and correct service selection.
- Confirm billing closure or final invoice policy (as applicable).
- Confirm provisioning rollback policy (if applicable).
 
## Operational Workflow

1. Open service → validate active state and dependencies.
2. Trigger Termination/Disconnection → select reason and effective date if used.
3. Validate downstream: AAA access revoked, sessions terminated as per policy.
4. Confirm billing closure behavior and data retention flags.
 
## Retention & Audit

- Operational records should remain queryable for audit for defined retention period.
- Do not hard-delete production entities unless explicitly approved and supported by policy.
 
## Common Issues

- Residual sessions after termination → check AAA session termination enforcement.
- Final invoice mismatch → check effective date and billing cycle alignment.
