Narrative:
I was on a down line to ZZZ for a seat problem on another aircraft on gate X. I was completing logbook signoff. A ramp agent informed me I was needed on gate X on a problem. I rushed over to gate X, aircraft XXX. The captain showed me the r-hand anti-ice valve was inoperative. I was thinking engine nose cowl anti-ice. I locked out the anti-ice valve, signoff to MEL valve, called maintenance control for number. I felt the pressure -- the aircraft had to leave soon. I finally got the number, put MEL sticker on logbook, handed the small sticker to captain to put on switch. And though at that time everything was done correctly, I sat down in the break room and reviewed the paperwork faxed to me from maintenance control. (Component/system/subsystem involved: anti-ice valve.) the paperwork was a copy from the MEL book. They handed me the paper after I locked out the engine nose anti-ice valve. I took the paperwork, glanced at it. 'Simple lockout per MEL,' I thought to myself, and stuck it in my back pocket. I reviewed the paperwork in the break room and realized it was wing anti-ice paperwork. I called maintenance control right away and verified it was wing anti-ice valve. I told them I locked out engine anti-ice. Then told me the aircraft was going to ZZZ1 and they told me they were going to correct the problem in ZZZ1.

Narrative: I WAS ON A DOWN LINE TO ZZZ FOR A SEAT PROB ON ANOTHER ACFT ON GATE X. I WAS COMPLETING LOGBOOK SIGNOFF. A RAMP AGENT INFORMED ME I WAS NEEDED ON GATE X ON A PROB. I RUSHED OVER TO GATE X, ACFT XXX. THE CAPT SHOWED ME THE R-HAND ANTI-ICE VALVE WAS INOP. I WAS THINKING ENG NOSE COWL ANTI-ICE. I LOCKED OUT THE ANTI-ICE VALVE, SIGNOFF TO MEL VALVE, CALLED MAINT CTL FOR NUMBER. I FELT THE PRESSURE -- THE ACFT HAD TO LEAVE SOON. I FINALLY GOT THE NUMBER, PUT MEL STICKER ON LOGBOOK, HANDED THE SMALL STICKER TO CAPT TO PUT ON SWITCH. AND THOUGH AT THAT TIME EVERYTHING WAS DONE CORRECTLY, I SAT DOWN IN THE BREAK ROOM AND REVIEWED THE PAPERWORK FAXED TO ME FROM MAINT CTL. (COMPONENT/SYSTEM/SUBSYSTEM INVOLVED: ANTI-ICE VALVE.) THE PAPERWORK WAS A COPY FROM THE MEL BOOK. THEY HANDED ME THE PAPER AFTER I LOCKED OUT THE ENG NOSE ANTI-ICE VALVE. I TOOK THE PAPERWORK, GLANCED AT IT. 'SIMPLE LOCKOUT PER MEL,' I THOUGHT TO MYSELF, AND STUCK IT IN MY BACK POCKET. I REVIEWED THE PAPERWORK IN THE BREAK ROOM AND REALIZED IT WAS WING ANTI-ICE PAPERWORK. I CALLED MAINT CTL RIGHT AWAY AND VERIFIED IT WAS WING ANTI-ICE VALVE. I TOLD THEM I LOCKED OUT ENG ANTI-ICE. THEN TOLD ME THE ACFT WAS GOING TO ZZZ1 AND THEY TOLD ME THEY WERE GOING TO CORRECT THE PROB IN ZZZ1.
