Narrative:
Flight from las vegas; nv. Requested and obtained clearance through pre departure clearance. Requested flight plan download using afis but it took several mins to download so it was decided to type the flight plan manually. During manual input the departure runway was selected as well as the appropriate SID (runway 19R/cowby 2 RNAV departure). Right after finishing typing the flight plan manually; the afis download arrived and it was decided to activate it. Immediately after departure; the FMS commanded a left turn to cowby intersection which was followed; but was contrary to the departure instructions so the tower instructed us to turn again to a heading of 180 degrees. At a later time we were cleared to continue on course. What we think happened is that the afis flight plan (active flight plan) did not know what runway we were going to use and because runway selection was done at an earlier time it was assumed to be there. The active plan was missing 4 waypoints due to not knowing the departure runway and that is why it commanded a left turn instead of an initial right turn.

Title: FA20 FLT CREW FAILS TO PROGRAM DEP RWY ON COWBY RNAV SID FROM LAS. TRACK DEV OCCURS WHEN FMS COMMANDS TURN DIRECT TO COWBY.
Narrative: FLT FROM LAS VEGAS; NV. REQUESTED AND OBTAINED CLRNC THROUGH PDC. REQUESTED FLT PLAN DOWNLOAD USING AFIS BUT IT TOOK SEVERAL MINS TO DOWNLOAD SO IT WAS DECIDED TO TYPE THE FLT PLAN MANUALLY. DURING MANUAL INPUT THE DEP RWY WAS SELECTED AS WELL AS THE APPROPRIATE SID (RWY 19R/COWBY 2 RNAV DEP). RIGHT AFTER FINISHING TYPING THE FLT PLAN MANUALLY; THE AFIS DOWNLOAD ARRIVED AND IT WAS DECIDED TO ACTIVATE IT. IMMEDIATELY AFTER DEP; THE FMS COMMANDED A L TURN TO COWBY INTXN WHICH WAS FOLLOWED; BUT WAS CONTRARY TO THE DEP INSTRUCTIONS SO THE TWR INSTRUCTED US TO TURN AGAIN TO A HDG OF 180 DEGS. AT A LATER TIME WE WERE CLRED TO CONTINUE ON COURSE. WHAT WE THINK HAPPENED IS THAT THE AFIS FLT PLAN (ACTIVE FLT PLAN) DID NOT KNOW WHAT RWY WE WERE GOING TO USE AND BECAUSE RWY SELECTION WAS DONE AT AN EARLIER TIME IT WAS ASSUMED TO BE THERE. THE ACTIVE PLAN WAS MISSING 4 WAYPOINTS DUE TO NOT KNOWING THE DEP RWY AND THAT IS WHY IT COMMANDED A L TURN INSTEAD OF AN INITIAL R TURN.
