The translation status for a segment is affected when it is split
or merged. If you split a segment, the status reverts to no status.
However, when you merge two segments, the status may change. For translation
status, if at least one segment has translated data (regardless of
whether the status is Manual, ICE, 100%, and so forth) the resulting
segment is marked Manual Translation and the review status is set
to None. (Depending on how your workflow steps are configured, the
review status could be set to Pending Review.) If the new segment
is untranslated, the review status is set to None.
For Studio file types, both parts of a split segment lose their translation
status and translated content. Merged segments also lose their translation
status, though the translated content is preserved.
Workflow information for the associated task is also affected, particularly
with merges that result in partially translated segments. Content
that has not been translated may be (incorrectly) counted as translated
in the workflow information.
