Why Do Analytics Reports Change After a Currency Conversion Update?

A currency conversion update can change historical totals when reports recalculate past transactions using a new rate or a different rate date. The change may be correct, but it needs to be distinguishable from new business activity.

What to check

Check the conversion source, effective date, rounding rule, base currency, report refresh, and whether historical rates are stored or recomputed. Trace a few transactions across source and report amounts.

Recommended next step

Document the chosen exchange-rate policy and how restatements are handled. Keep rate metadata with converted values and notify report owners when historical totals are recalculated.
