# Validation Message Contract Definition
## Description
A validation messages contract holds all of the validation messages for a particular business object. There is one validation message contract per business object.For example, the validation message contract for the Order business object is called BO_Order_ValidationMessages. Individual validation messages in the validation messages contract can be called from Validate methods (business logic contracts).  Each validation message can be referenced via its name. In the Validate method, the "messageID" refers to the value of the "name" attribute of the validation message.
