When a smart code series is changed, it does not take effect on an account immediately.
The Account ALREADY calculated when the next date an action will take place.
AFTER that action it will look at the Smart code series to calculate the action for the next sequence.
How it looks on the account.
S/code Series XX Sequence # 3 Next 3/12/25
So the account HAS TAKEN the Sequence #3 action, and stays in Sequence 3 UNTIL the "Next" date of 3/12/25 when it can move on to Seq. #4 etc.
