It was originally meant to be a full report of all financial account activity, but that much data would cause issues.
You are correct, currently the focus is only on key identifying details and summary values for each reportable account.
But with the rise of AI everyone should assume full account transaction information is sent, as it will only be a matter of time before they'll be able to sift, scan & utilise line‑by‑line account transaction history.
