Which batch status signifies that the batch is checked out but not yet checked in?

The "In Progress" status clearly indicates that a batch is currently being worked on or processed, meaning it has been checked out for modifications or updates but has not yet been finalized or checked back in. This status implies active engagement with the tasks at hand, suggesting that the batch is still under consideration and is not ready for further actions, such as archiving or marking as completed.

Conversely, the other statuses denote different phases of the batch lifecycle. "Null" suggests that there is no applicable status assigned, which does not apply to a batch that's actively being worked on. "Completed" indicates that all necessary actions have been finished, while "Archived" signifies that the batch has been finalized and stored away, making them inappropriate choices for a batch that is still in the process of being worked on.
