What does "Last Action Taken" mean?

[DerGreif]

Hello together,

I am new here and have just one question:
What does the entry in "Last Action Taken" refer to? Is it the date of the latest revision of the aircraft profile or is it the date of the last action undertaken of the aircraft or the date of the last action taken with respect to the aircraft? Because there is one particular entry where the date of "Last Action Taken" is earlier than the date of deregistering. I found that odd.

THank you for any answers in advance!

Kind regards,
G.
