Rules for Step Type Option

You can control who can change a segment's status with the Step Type option, which is available for all Human Steps in a workflow on the Advanced options pop-up. The Step Type can be None (the default), Review, or Translate. Depending on the Step Type selected for the current step, the Browser Workbench restricts the status modification options available to the user. The Step Type option also defines how modifications to a segment content affect the status of the segment.
Note: If you are working on an asset in ad hoc mode (that is, outside of a workflow) the Step Type restrictions do not apply. It is equivalent to a having a Step Type of None.
A Step Type of None has the following effect on the user that performs the Human Step:
A Step Type of Translate enforces the following restrictions in Browser Workbench for the user that performs the Human Step:
A Step Type of Review will enforce the following restrictions in Browser Workbench for the user that performs the Human Step:

These rules make sure that a translator cannot approve anything and cannot change anything already approved without triggering an additional review. On the other side, the reviewer cannot change anything without approval from the translator.

If a status change was made by mistake and a user does not have permission to undo it according to the rules above, then the user can restore the previous status by rolling back the segment to the last history entry.

If a segment is locked then no status change is available on the segment.
