Did you know when the Action Text in a trigger is changed, why the Change Analysis Report that is produced by RC/Compare does not compare the triggers?
Please have a look at the TRIGGER ACTION_TEXT ruleset.
By setting rule ACTION_TEXT to N RC/Compare will not find the changes by leave and it as is.
You need to change his rules this way:
ACTION_TEXT Y
OBJECT_CREATOR N
OBJECT_NAME Y
REMAINING_TEXT Y
Then RC/Compare will find the changes in the trigger ACTION_TEXT.
