To provide general information and introduction to the Central Purchasing also known as Purchasing HUB.


The Central Purchasing solution is a new way to connect multiple ERP/S4 systems and Ariba system to a HUB S4 system, to create a centralized purchasing process.

With centralized purchasing employees and purchasers can create documents in the HUB system and send them to a connected system to be sourced and processed.

In addition, purchasing documents can be extracted from the connected system to the HUB system for sourcing and central purchasing.

The transfer and extraction are both processes which are initialized from the HUB system. 

ERP systems must have the add-on: HUBERPI to be a connected system as detailed in SAP Note 2491065.

S4 systems have the capability to be central system, but it can only be a connected system if the add-On: HUBS4IC is installed as detailed in SAP Note 2573672.
If an S4 system acts as a central and connected but on different clients, the add-on: HUBS4IC must be installed.

The capabilities of Central Purchasing (HUB) are:

  • Central Sourcing
  • Central Requisitioning
  • Manage Central RFQs
  • Create Purchase Order Centrally
  • Central Purchase Contracts
  • Business Processes Automation
