Please add the Same-SKU attribution metrics from the Amazon Ads API v3 spAdvertisedProduct report to the Sponsored Products advertised product report (sponsored_products_advertised_product):
Why: the current units/sales/purchases fields include sales of any SKU bought after a click on the advertised ASIN (other colours, sizes and products). Without the Same-SKU split we cannot tell how many attributed units were the advertised ASIN itself, so per-ASIN organic sales (ordered units minus ad-attributed units) come out overstated on sibling variants and understated on the advertised one.
These columns are standard in the Amazon Ads API v3 report and are available at 1d, 7d, 14d and 30d. 7d and 14d would cover our needs.
