One reusable marker for “this number was converted”, so every rolled-up figure stays auditable — rate & date, one hover away.
Every money figure has two identities. Its native value — what was actually paid or billed — and its reporting value, converted into the org rollup currency so it can be summed. This marker makes that duality legible without cluttering the 95% of views that are single-currency: it only ever appears on a figure that was actually converted, and the default single-currency org sees none of it.
locked at booking · 12 Jun (rate frozen when the cost/invoice was booked). Forecasts read latest rate · 12 Jun and can go stale.When a total blends several locked rates there’s no single rate to show, so the popover reads “blended from N locked rates” and links to the breakdown rather than faking one number.
