Explanation

In SAP BW generic DataSource delta extraction, the delta mechanism needs a field that reliably marks when or in what order a record was created or changed. Numeric pointer (C) works because it increments monotonically, so new/changed records always have a higher value than previously extracted ones. Time stamp (D) captures the exact date-time a record was modified, and Calendar day (E) captures the date of change - both allow the system to filter records newer than the last extraction.

Amount (A) and Quantity (B) are wrong because they are business measure fields (e.g., revenue, units sold) - their values fluctuate up and down and carry no inherent information about when a record changed, making them useless as a change marker.

Memory tip: Think "Can this field tell me WHEN or IN WHAT ORDER a change happened?" If yes (timestamp, calendar day, incrementing pointer), it qualifies. If it just tells you HOW MUCH (amount, quantity), it doesn't.
