Narrative:
I received the clearance via pre departure clearance for the leg. The flight plan filed by dispatch was a non-standard route; which I was aware of. Our flight plan showed us filed on the WEVIC1 dta transition. Upon receiving the clearance; I overlooked that we were now cleared to fly the wevic 1 departure; bld transition. My error occurred in reading the clearance via pre departure clearance; not with building the flight plan on the FMC. As we were flying the wevic 1; we made a turn towards dta (following the transition we thought we were cleared). Center asked us where we were going. After a short discussion on the frequency; we discovered that we were cleared on the bld transition; not the dta transition that we were flying. We were then cleared direct to bld. A follow up phone call was made to center once we landed. We discussed the situation in detail and I told him my error was in overlooking the change in the clearance on the pre departure clearance. He said he just wanted to discuss the situation; as there have been many similar deviations in recent months. He said there was not a loss of separation. A closer attention to detail when receiving a clearance via pre departure clearance would prevent this from happening again.

Title: B737-700 FO FAILS TO NOTE CHANGE IN SID TRANSITION ON THE PDC CLRNC. TRACK DEV RESULTS.
Narrative: I RECEIVED THE CLEARANCE VIA PDC FOR THE LEG. THE FLIGHT PLAN FILED BY DISPATCH WAS A NON-STANDARD ROUTE; WHICH I WAS AWARE OF. OUR FLIGHT PLAN SHOWED US FILED ON THE WEVIC1 DTA TRANSITION. UPON RECEIVING THE CLEARANCE; I OVERLOOKED THAT WE WERE NOW CLEARED TO FLY THE WEVIC 1 DEPARTURE; BLD TRANSITION. MY ERROR OCCURRED IN READING THE CLEARANCE VIA PDC; NOT WITH BUILDING THE FLIGHT PLAN ON THE FMC. AS WE WERE FLYING THE WEVIC 1; WE MADE A TURN TOWARDS DTA (FOLLOWING THE TRANSITION WE THOUGHT WE WERE CLEARED). CENTER ASKED US WHERE WE WERE GOING. AFTER A SHORT DISCUSSION ON THE FREQUENCY; WE DISCOVERED THAT WE WERE CLEARED ON THE BLD TRANSITION; NOT THE DTA TRANSITION THAT WE WERE FLYING. WE WERE THEN CLEARED DIRECT TO BLD. A FOLLOW UP PHONE CALL WAS MADE TO CENTER ONCE WE LANDED. WE DISCUSSED THE SITUATION IN DETAIL AND I TOLD HIM MY ERROR WAS IN OVERLOOKING THE CHANGE IN THE CLEARANCE ON THE PDC. HE SAID HE JUST WANTED TO DISCUSS THE SITUATION; AS THERE HAVE BEEN MANY SIMILAR DEVIATIONS IN RECENT MONTHS. HE SAID THERE WAS NOT A LOSS OF SEPARATION. A CLOSER ATTENTION TO DETAIL WHEN RECEIVING A CLEARANCE VIA PDC WOULD PREVENT THIS FROM HAPPENING AGAIN.
