Narrative:

Ferra RNAV departure. At some point the points scabi and cds dumped out of the departure points. They were checked on the ground; but after we passed ferra; I noticed it was direct to panhandle. As I was checking the departure paper page; ATC asked us if we were on the departure as they were directing a radio change. Not sure if captain accidentally deleted them or what. I was still hand flying at that point. Next controller asked us where we were going and then cleared us direct to panhandle.supplemental information from acn 701374: FERRA2 pnh departure from dfw. Misunderstood/misprogrammed CDU. Dropped scabi and cds from CDU and flew from ferra directly pnh.
