To filter records entering a journey based on an updated status field (“shipped”), the marketer should use:

An Entry Source Filter to limit which contacts actually enter the journey at the point of entry (e.g., only those whose order status is 'shipped' today).

An SQL Query to preprocess or segment records within a Data Extension before injecting them into the journey.

Filter Activity is used inside Automation Studio (not at the journey entry point), and Decision Splits occur after entry — not before.
