Generally speaking, FlexCard and Gateway are two separate purchasing processes.
The only time that they two processes intermingle is when a FlexCard transaction requires a purchase order as back-up in order to raise a limit on a card or to purchase a restricted item.
You can create a purchase order in the system using the FlexCard Authorization Form. View instructions for use of the form in Gateway.
This form will go through your departmental approval process and will then route to the FlexCard Team to raise your limit or to approve of the restricted item.
Once they approve, you will get a purchase order number to confirm that your limit has been raised or your restricted item has been approved.
The FlexCard purchase order begins with an "F" rather than a "GW" and automatically closes so that invoices cannot pay against it.
