Posts a new order to MyAdmin. Create a ApiOrderHeader with details of the order. Required ApiOrderHeader fields are:
devicePlanLevel
forAccount
orderItems
purchaseOrderNumber
shipToId
shippingFeeId
warrantyOptionId
Note that an Order which contains OrderItems for which a Bulk Price exists may be adjusted for applicable Bulk Price discounts. To take advantage of these discounts, either post an order with the desired quantity at the normal purchase price (the discounts will be applied automatically) or post an order with exactly BulkPriceMinQuantity (see ApiProductPricing) quantity at the normal purchase price, and any additional quantity using the BulkPrice. Other combinations of order items may result in errors.
