How does PCMCS support audit trails and documentation?

The choice that states PCMCS supports audit trails and documentation by maintaining detailed records of financial data and changes for compliance is correct because it highlights the system's capacity to track and log every modification made to financial information. This feature is crucial in ensuring accountability and transparency in financial reporting, which is essential for compliance with various regulatory standards. By keeping a meticulous history of changes, users can trace back through the data to understand the context and reasoning behind financial decisions, thereby facilitating audits and reviews. This focus on documentation plays a pivotal role in risk management, helping organizations to manage financial data effectively and to provide necessary evidence during audits.

Other choices either suggest a lack of record-keeping, reliance on informal methods, or limiting records to physical formats, all of which would undermine the integrity and effectiveness of the audit trail capabilities that PCMCS is designed to provide.
