Narrative:
Upon initial programming of the FMS, the 'company route' stored in the FMS was verified with the 'canned route' instead of the filed route on the flight release. The company recently changed from using 'canned' flight plans to filing individual flight plans. The rtes were the same until mem where the 'canned' route was mem J29 pxv and the filed route was mem J35 fam. Passing mem and joining J29 the center controller advised that we appeared east of course. We realized the error, corrected the FMS routing to the filed routing and corrected course. Fatigue contributed. The previous day was a 13.5 hour duty day with 7.5 block flight time followed by 10 hours rest with an XB50 (body clock time zone) report. XA00 body time get up.

Title: AN ACR B737 FLC GOT OFF COURSE WHEN THEY LEFT THE CANNED FLT PLAN IN THE FMS INSTEAD OF THE 'AS CLRED' FLT PLAN.
Narrative: UPON INITIAL PROGRAMMING OF THE FMS, THE 'COMPANY RTE' STORED IN THE FMS WAS VERIFIED WITH THE 'CANNED RTE' INSTEAD OF THE FILED RTE ON THE FLT RELEASE. THE COMPANY RECENTLY CHANGED FROM USING 'CANNED' FLT PLANS TO FILING INDIVIDUAL FLT PLANS. THE RTES WERE THE SAME UNTIL MEM WHERE THE 'CANNED' RTE WAS MEM J29 PXV AND THE FILED RTE WAS MEM J35 FAM. PASSING MEM AND JOINING J29 THE CTR CTLR ADVISED THAT WE APPEARED E OF COURSE. WE REALIZED THE ERROR, CORRECTED THE FMS ROUTING TO THE FILED ROUTING AND CORRECTED COURSE. FATIGUE CONTRIBUTED. THE PREVIOUS DAY WAS A 13.5 HR DUTY DAY WITH 7.5 BLOCK FLT TIME FOLLOWED BY 10 HRS REST WITH AN XB50 (BODY CLOCK TIME ZONE) RPT. XA00 BODY TIME GET UP.
