I'm also interested in this question of how to check an actual e-ticket number as I am in the same situation. The last segment of an Award trip amended, and the amendment does show up in the trip summary in CMT as 'confirmed'.

However when I look at the e-ticket tab only the first two legs show up and the last leg isn't on there. Also the status shows the date of the original issue of the ticket not the amendment.

I did contact Pre Travel Support who put me through to the ICC and they confirmed that they could see all segments of travel.

My concern is that when I show up at the airport the E-ticket is no longer valid for the last segment.
