Function documentation Vendors: Partner Determination for Vendor Hierarchy Nodes Locate the document in its SAP Library structure


During purchase order processing, the system automatically determines special partner functions in the partner data of the document. The system uses these partner functions for the following purposes:

        To determine the hierarchy path and store it in the document

        To store hierarchy data per item (the pricing of individual items in the purchase order may relate to different hierarchy nodes)


In the purchase order, the system determines a default partner function (2A in the standard SAP system), based on the hierarchy category. The system then uses partner determination (controlled through Customizing for Vendor Hierarchies (Purchasing) in the activity Define Partner Determination for Hierarchy Categories) to find higher-level partner functions, until it has determined the complete hierarchy path for the purchase order. The standard version of the SAP system includes four standard partner functions for this purpose, namely 2A-2D. You can add as many additional partner functions as you require, up to a maximum of 15 levels.


The following example shows how the system uses partner determination to create the hierarchy path in a purchase order. In the following vendor hierarchy a purchase order is placed with vendor 2743.


This graphic is explained in the accompanying text


Using partner determination, the system creates the correct hierarchy path by establishing which higher-level partners apply. The partner function 2A is defined in Customizing as the default partner function. The vendor has the partner function VN (vendor). In this example, the system determines the following hierarchy path and stores it as partner data in the purchase order:

Partner functions and corresponding nodes/vendors

Partner function


2C (node - top level)


2B (node - second level)


2A (node - third level)
