'data' is the value returned by the method.

Remarks

Amount of the discount for each line item (if any).

This property contains the amount of any discount applied by the merchant to this line item. This property should be empty (or zero) if the ItemUnitCost reflects a discount price or if no line item discount applies.

This amount is to be presented with an implied decimal point. For example, US $10.00 must be represented as 1000, and $0.10 is likewise simply 10. The allowable number of significant digits as well as the positioning of any implied decimal point is dictated by the designated CurrencyCode configuration setting. In the United States (default), the number of allowable significant digits is seven. Thus the maximum TransactionAmount is "9999999", yielding a US dollar amount of $99,999.99. This property may not contain a negative number. All properties associated with a specific Line Item must be set with an identical ItemIndex index. This index must be incremented for each Line Item that is added. The ItemIdx ranges from 0 to LineItemCount - 1.

This property is used for both Visa and MasterCard Corporate Purchasing Cards.

The size of the array is controlled by the LineItemCount property.

This property is not available at design time.
