Business Purpose
With this customization, you define organizational elements (company codes, plants, purchasing organization) that you would like to use in the SAP Ariba Direct Materials Sourcing and Central Purchase Contract process. The organizational elements are also assigned to a logical system (in the hub scenario). This will enable the system to recognize which back-end system is involved in the process (for example, for the local contract creation scenario).
In this customizing, you also mark specific organizational elements as active if you would like to use them in SAP Ariba Central Procurement. The activation is applicable for all processes in the Procurement Hub (for example, Central Purchase Contracts and SAP Ariba Direct Materials Sourcing).
Technical Explanation
During the setup of central procurement, you also need to define connected systems and assign company codes, plants, and purchasing organization. The logical system ID can be copied over from transaction SCC4. Once the organizational elements are defined, you will need to add the connected system to an RFC destination.
Note
The last step is only required in the hub scenario.
