What does the "In Progress" status mean for a batch?

The "In Progress" status signifies that the batch has been actively checked out for processing but has not yet been checked back in. This indicates that work is ongoing, and the data or items within the batch are currently being reviewed or modified. The workflow suggests that the batch is engaged in an active process, which contrasts with statuses like "not yet started," "completed," or "awaiting approval." Each of those alternatives describes different stages of the batch's lifecycle, but "In Progress" specifically indicates that tangible actions are being taken on the batch, while still pending its finalization or submission back into the system.
