Hi, Steven. This video (by Paul) may not be directly related to your case (?), but I least explains the basic concepts when dealing with the translation of Word documents with tracked changes (since the original file is an IDML file, for that there is also the toggle feature "Process documents with changes tracking" in the Adobe InDesign CS4-CC IDML file type): Translating tracked changes in Studio 2015: 

Hope it helps, at least conceptually, since you are dealing with a bilingual review docx file. I have it already in my bookmarks. Really useful.

Hi Paul (pfilkin) , I omitted one piece of information that might make sense to you. When we got the reviewed bilingual doc back, the segment IDs were completely changed on each row, as shown below.

To resolve this issue, I used the original bilingual review to import all changes from the reviewed version. 

Have you any idea how this might have happened? We had instructed our client to save the bilingual review file on their desktop before making changes and I can't imagine they inserted these manually.

Thanks,

Steven

My pleasure! I concur, Steven. Some times clients don't follow instructions, even don't know what they're doing, and come back to you with strange requests or issues. Your screenshot showing the segment IDs (coming from your client) is strange, in the first place. Segment IDs are regular numbers, integers, not GUIDs (global unique identifiers) as shown. Secondly, this Studio feature works perfectly well (as long as the client edits the targets segments ONLY leaving alone the tags and the source text). But the way, what a nice feature! This is one of those cases where it is not about Studio but about something else, like the client's operating system, Office settings, not following instructions, etc. Go figure. The bilingual file review procedure is straightforward (I include these links for other readers, of course): http://producthelp.sdl.com/sdl_trados_studio_2015/client_en/edit_view/AboutReviewingFilesExternally.htm | http://producthelp.sdl.com/sdl_trados_studio_2015/client_en/edit_view/UpdateExternallyReviewedFiles.htm

Paul (pfilkin) ,

It looks like the Segment IDs that have come from the client's review are a concatenation of Translation Unit IDs and Segment IDs. For example, this is what we see in the sdlxliff for Segment 1, which follows the same pattern throughout. 

This is what we see in the reviewed bilingual file in the Segment column for Segment 1:

My question now is: how could our client end up sending us back the bilingual review with these IDs replacing the original ones?

Good question... I think you'll only know if your client is 100% honest and detailed about the history of the bilingual review file you sent him.  These files are pretty sensitive as we embed informamtion into the docx so opening in other tools, older versions of Word, saving as a different version of Word and back again etc... these are all things that have the potential to cause problems.

If you ever find out we can add it to the long list of things that can go wrong!
