What can be said about the accessibility of workflow instance fields?

Workflow instance fields in NetSuite are designed to be specific to individual workflow instances. This means that they hold data or state relevant to a particular execution of a workflow and are not shared among different workflows. As a result, these fields maintain their integrity and scope, allowing for personalized tracking and data management within each workflow.

This encapsulation is important for ensuring that different workflows, which may have similar fields but operate under distinct circumstances and logic, do not interfere with each other's data. Only the specific workflow that creates or modifies an instance can access its respective fields, supporting better organization and management of process-specific data without the risk of conflicts or unintended data sharing.
