The rows are **concatenated, never summed across accounts**: if you query total spend with no dimensions across 3 accounts, you get 3 rows (one per account), not one combined row. To tell the rows apart, add the **Account Name** or **Account ID** dimension. Without it, rows from different accounts look identical and a multi-account daily report becomes ambiguous: three accounts produce three rows for the same date. ## Currencies and Timezones Each account reports in its own currency and timezone, and Detrics returns the values exactly as the platform reports them, with no currency conversion. Summing spend across a USD account and an ARS account produces a meaningless number; keep mixed-currency accounts in separate rows or convert in your destination. ## Errors on Individual Accounts If access to one of the accounts was lost (a removed permission or a deactivated account, for example), Detrics still returns the data from the remaining accounts, together with a warning identifying the affected account. Any other error stops the whole query, so you never receive silently incomplete totals. See [Troubleshooting Connections](/connect/troubleshooting-connections) for fixing access issues. ## Next Steps The building blocks of every query Why recent numbers shift, and when data becomes final
