For merchants who are submitting tab-delimited adjustment files, this error occurs when the item-promotion-id or ship-promotion-id value is not recognized. This value should be the same as the item-promotion-id or shipping-promotion-id value provided in your orders report.
For merchants who are posting XML feeds, this error occurs when the MerchantPromotionID value in your order adjustments feed is not recognized. This value should be the MerchantPromotionID value provided in your orders report.
If your orders report contained no value for item-promotion-id, shipping-promotion-id or MerchantPromotionID, do not provide a value such as "none" or "N/A" in your adjustments file or feed. You should leave the value blank.
To resolve this error, please resubmit your data with a valid item-promotion-id, ship-promotion-id or MerchantPromotionID value.
