Invalid MerchantOrderID. For help on how to proceed, see http://sellercentral.amazon.com/gp/help/30681
This error occurs when we are unable to recognize the
MerchantOrderID you provided. The MerchantOrderID must exactly match a
value you previously provided in an order acknowledgment feed. Common
reasons why this error may occur include:
You accidentally provided the AmazonOrderID instead of your own MerchantOrderID.
You transposed or omitted characters in your MerchantOrderID.
Your MerchantOrderID was never created in the Amazon.com system because of an error in a previous order acknowledgement feed.
To resolve this error:
Review the MerchantOrderID field. If the AmazonOrderID is in that
field, provide a valid MerchantOrderID. If the field has a typo,
Update your acknowledgment feed with the corrected MerchantOrderID and resubmit your data.
