Performing an entity-level controls analysis helps the auditor understand the overarching framework of activities and subprocesses within the accounts payable function. This approach provides a high-level view of the control environment and how different processes interrelate and contribute to the overall control objectives. By understanding the framework, the auditor can identify key controls, assess their design and implementation, and determine areas of potential risk. This foundational understanding is crucial before delving into more detailed, transaction-level testing.
