Ariba Network Information for Vendors

Impacted Location List
Frequently Asked Questions

We are pleased to announce a new initiative to streamline our procurement and accounts payable processes. Marathon Petroleum Company, LP (MPC) is partnering with SAP Ariba® to fulfill our vision of moving away from paper and manually transmitted documents by implementing Ariba Network. The Ariba Network allows for a collaborative approach toward the shared aspects of business commerce (proposals, contracts, orders, invoices, and payments).  

The current project scope is limited to Purchase Orders (POs) for a subset of MPC locations. These POs will have a number sequence beginning with 45******** and will typically be for one of the locations on the list above.  

POs from any other location with a number sequence beginning with 41********, POs for vendors engaging with MPC through the Track system, and POs for Hydrocarbon, Transportation, Freight, Real Estate, Banking, Telecommunications and Utility transactions will not be transitioning at this time and will continue to be processed as they are today (no change). In addition, MPC is not transitioning non-PO activity to Ariba Network. 

In Q3 of 2022, MPC will be transitioning our existing landscapes into a new, integrated procurement and accounting system. At that time, MPC will be moving to a different Ariba Network connection as we prepare to roll out the Ariba Network companywide. Additional communications will be provided in advance of this change.
