SAP and P2P Integration Use Cases: Purchase-to-Order, Storefront and Multi-ERP


Three common use cases that arise in in P2P implementations include purchase-to-order, storefront and multi-ERP scenarios (sometimes within the same deployment all together, often individually). Let’s explore these in more detail:

Procure to order – This is one of the most common areas to consider. In this scenario, the P2P solution manages the process from the purchase requisition through the issuance of the purchasing order. Integration with ERP helps bring master data to the P2P solution, and after the PO is issued, this data flow goes back to ERP. This way, all invoice processes run through the ERP.

Storefront – Some procurement organizations prefer to proceed with all requisitions, POs, approvals and invoicing processes executed in the ERP modules, but then take advantage of the more robust shopping functionality (aka storefront) available in modern web-enabled P2P solutions. In this scenario, users shop for goods and services using the storefront functionality of the P2P solution, while completed shopping carts are sent back to the ERP for approval.

Multi-ERP – The above scenarios do not restrict customers from having multiple ERPs integrated into a single P2P solution. In such cases, the design complexity derives from the increased number of decisions for process mapping and business rules – specifically different accounting structures, multiple transactional tables, user restrictions (to view transactions), different sets of approval rules, content groups used to drive users to specific content based on the ERP system, etc.

This post is based on the Spend Matters white paper, Cloud P2P Deployment: A How-To Guide to SAP and ERP Integration with eProcurement and Beyond (free download). Authored by Xavier Olivera, director of P2P research, Jason Busch, founder and managing director, and Thomas Kase, vice president of research, it features a range of lessons learned from the P2P implementation trenches.
