Error 13003

There is an error in the RestockDate value you submitted. For help fixing this, see http://sellercentral.amazon.co.uk/gp/help/24821

This error occurs when you provide an invalid RestockDate value in your inventory feed. For the RestockDate value to be valid, it must be:

• Formatted as YYYY-MM-DD.
  For example, February 29, 2008, must be formatted as 2008-02-29.
• A date in the future.

To resolve this error, please post a modified inventory feed using a properly-formatted, future RestockDate.
