Narrative:

On jul/sat/03, aircraft X came to ZZZ from ZZZ1 with a vertical seat adjustment on the first officer's seat on MEL. I xferred it from a yellow sticker to a white MEL sticker assuming that all the correct procedures had been followed allowing the plane to leave. The plane continued on to ZZZ2 where the first officer's seat was fixed. Later, it came to my attention that the vertical cable was supposed to be disconnected before the plane left ZZZ.
