Los campos de costo y tarifa siempre se reportan en microcentavos.

The statement is false because cost and rate fields in Amazon Marketing Cloud (AMC) are typically reported in standard currency units (e.g., dollars, euros) or their smallest fractional units (e.g., cents), not specifically microcents. While AMC handles granular data, the default reporting for financial metrics like cost and rate aligns with conventional currency representations to ensure clarity and usability for advertisers. Reporting in microcents would be an unnecessary level of precision for most analytical and reporting needs and is not the standard practice within the platform.
