Narrative:
On the ground we received ATC clearance via cpdlc (controller pilot data link communication). There was an amendment of the [SID] to fly the holtz 1 transition. We loaded that to the CDU with the clearance prompt; then accepted the clearance. However there was no change to our filed route other than the [SID] HOLTZ1 vs. LOOP8. Enroute ATC asked if we were proceeding on course to pke. We advised no; we were proceeding to dag as filed. ATC then gave us a vector and a new route. Apparently ATC had us on a completely different route than we had on the [flight plan]. This was not given to us from cpdlc. The only change shown was the [SID]. There was no conflict with traffic. And we established a new route with ATC. Somewhere there was a disconnect between the filed route and our clearance.
