What is necessary to debug a flow or view test run details in Flow Builder?

To debug a flow or view test run details in Flow Builder, having the ability to view all data is essential. This level of access allows the user to gather all relevant information about the flow's execution, including the data that was processed during the test run. When debugging, it is crucial to see the complete context in which the flow operates, including variable values and record states, to identify the causes of any issues or unexpected behavior.

While other permissions, such as customizing applications or managing flows, might contribute to a user's overall ability to work with Salesforce, they do not provide the specific visibility into the data necessary for effective flow debugging. Without the capability to view all data, a user would lack critical insights that would inform necessary adjustments or corrections to the flow configuration. Thus, having access to all data is key to successfully diagnosing and resolving issues within the flow.
