You are trying to set columns in FIN_TRANSACTION using a correlated update
from GTT_AI_FIN_TRANSACTION but you haven't actually included a join to the
GTT.
I think you would need something like this (which you could test for syntax
outside your trigger code)
UPDATE fin_transaction
JOIN gtt_ai_fin_transaction ON fin_transaction.transaction_nbr =
gtt_ai_fin_transaction.transaction_nbr
SET fin_transaction.after_balance_amount =
gtt_ai_fin_transaction.after_balance_amount,
fin_transaction.after_status = gtt_ai_fin_transaction.after_
status
;
However you may then find yourself tripping over mutating table ORA-04091 (as
you are updating the same table that the trigger is defined against).
