Answer:

Method validateWrite() will just check mandatory fields and is triggered when the record . Checks made by validateWrite() are the same as the super() call in validateField().So if your condition is not related to the value an application user enters in a specific field, you should put the validation in validateWrite().

    /// Validate record
    /// </summary>

    public boolean validateWrite()
    {
        boolean             ret                 = true;
        atnylaProgramTable     atnylaProgramTable;
        ret = this.validateData();       
        // record-level validations
        if (ret)
        {
            ret = this.checkDateOverlap();
        }  
        if (ret)
        {
            ret = super();
        }
        return ret;
    }
