Minimum Advertised Price is also known as MAP. This error occurs when the MAP value in your inventory file or price feed is invalid.
To be valid, your MAP value must be a positive value. For example, "3.00" is a valid value, but "-3.00" is invalid.
To resolve this error, please resubmit your data using an MAP value that is greater than zero.
