What must be enabled for a user to enter a record into a workflow process?

For a user to enter a record into a workflow process, it is essential that the workflow is active and operational. An active workflow signifies that the system is currently set to process records within that workflow framework, allowing users to initiate and progress through the stages of the workflow. Without an active workflow, any attempts to enter records would be futile, as the foundational structure that governs the workflow's rules and steps would not be functional.

The other options touch on aspects that are related to workflow management and user permissions but do not directly contribute to the capability of entering records into an active workflow process. For instance, while user permissions are important, even if a user has sufficient permissions, they still cannot enter a record if the workflow itself is not active. Similarly, the concepts of pre-approval for records and the requirement that all workflows must be completed first are not standard prerequisites for entering a new record into an ongoing workflow process.
