FDMS North Purchasing Card Line Item Parameters
Line item data (Level 3) describes the details of the item purchased and can be passed for each
transaction. The convention for passing line item data in name-value pairs is that each name-
value starts with L_ and ends with n where n is the line item number. For example L_QTY0=1
is the quantity for line item 0 and is equal to 1, with n starting at 0. In addition, the
SHIPFROMZIP parameter is required for Level 3 transactions.
