What is a best practice regarding system context relating to flows?

Choosing to configure a flow to run in system context without sharing is a best practice because it allows the flow to operate with elevated privileges. This means that the flow can access and modify records that the running user might not have permission to access under normal circumstances. System context means that the flow's execution is not limited by the security and sharing rules that are typically enforced in Salesforce, which is essential for automation tasks that require broader visibility and access to data.

This configuration is particularly useful in situations where automation needs to perform actions based on business logic that the current user's privileges would otherwise restrict. For example, an automated process might need to update records in a way that requires access to sensitive information or records that the user does not typically have visibility into.

It's important to note that while this approach provides powerful capabilities, it should be used judiciously to avoid unintended data exposure or modifications that could lead to security issues. Understanding when and how to use system context without sharing is crucial for maintaining the integrity and security of an organization’s data.
