def batch_meter_usage(UsageRecords=None, ProductCode=None):
    """
    BatchMeter is called from a SaaS application listed on the AWS Marketplace to post metering records for a set of customers.
    For identical requests, the API is idempotent; requests can be retried with the same records or a subset of the input records.
    Every request to BatchMeter is for one product. If you need to meter usage for multiple products, you must make multiple calls to BatchMeterUsage.
    BatchMeterUsage can process up to 25 UsageRecords at a time.

            (dict) --A UsageRecord indicates a quantity of usage for a given product, customer, dimension and time.

            Your application can meter usage for up to one hour in the past.

            Dimension (string) -- [REQUIRED]During the process of registering a product on AWS Marketplace, up to eight dimensions are specified. These represent different units of value in your application.
            Quantity (integer) -- [REQUIRED]The quantity of usage consumed by the customer for the given dimension and time.
            
            

    :type ProductCode: string
    :param ProductCode: [REQUIRED]

    DuplicateRecord - Indicates that the UsageRecord was invalid and not honored. A previously metered UsageRecord had the same customer, dimension, and time, but a different quantity.
