For testing and debugging. When true, the dataset starts with one extra row (recordType "run-report") holding per-input status, item counts, null counts and errors, followed by the product rows. That extra row counts as one charged result, and it is written even when the run ends FAILED, BLOCKED or ROBOTS_BLOCKED (not for INVALID_INPUT). Per-input status rows are never separate dataset items and are not charged. The same report is always saved free as RUN_SUMMARY in the key-value store. Leave false for normal use so the dataset holds only products.
