nullify

I'm a little stuck... Click here to teach me more about this clue!

'cancel a procedure' is the definition.
'nullify' can be an answer for 'cancel' (nullifying is a kind of cancelling). I am unsure of the 'a procedure' bit.

'fully in order' is the wordplay.
'order' indicates anagramming the letters.
'fully'+'in'='fullyin'
'fullyin' anagrammed gives 'NULLIFY'.

'that's' is the link.

Can you help me to learn more?

(Other definitions for nullify that I've seen before include "quash" , "Abrogate" , "Make invalid" , "Bring to naught" , "Cancel, abolish" .)

I've seen this clue in The Globe and Mail.
