... immediately after that putting her note up for revision (9)
I believe the answer is:
thereupon
'immediately after that' is the definition.
(I've seen this before)
'her note up for revision' is the wordplay.
'for revision' indicates an anagram (I've seen this in other clues).
'her'+'note'+'up'='hernoteup'
'hernoteup' is an anagram of 'THEREUPON'.
'putting' is the link.
(Other definitions for thereupon that I've seen before include "immediately after that" , "straight afterwards" , "at that point" , "Shortly after that" , "straightaway" .)
