Narrative:
Air carrier X called climbing to 3000 ft. I was having trouble assigning a heading to another aircraft. I was busy at the time. Standard departure heading is 150 degrees. Before I could get back to air carrier X, air carrier Y departed on standard 120 degree heading. I observed air carrier X on same heading as air carrier Y. I asked air carrier X his assigned heading. He said initially it was 170 degrees but when shipped to departure frequency, he was assigned runway heading. I issued an immediate right turn to 240 degrees.

Narrative: ACR X CALLED CLBING TO 3000 FT. I WAS HAVING TROUBLE ASSIGNING A HDG TO ANOTHER ACFT. I WAS BUSY AT THE TIME. STANDARD DEP HDG IS 150 DEGS. BEFORE I COULD GET BACK TO ACR X, ACR Y DEPARTED ON STANDARD 120 DEG HDG. I OBSERVED ACR X ON SAME HDG AS ACR Y. I ASKED ACR X HIS ASSIGNED HDG. HE SAID INITIALLY IT WAS 170 DEGS BUT WHEN SHIPPED TO DEP FREQ, HE WAS ASSIGNED RWY HDG. I ISSUED AN IMMEDIATE R TURN TO 240 DEGS.
