Our Future – Integrated Business Suite with SAP One Domain Model

In previous blog post we gave you some insights and basic understanding of SAP One Domain Model and technical concept behind it.  To summarize it again: as you already know, the Intelligent Enterprise Suite at SAP provides next generation customer experience by delivering E2E integrated, intelligent solution for each line of business across different business solutions and applications. To ensure a smooth communication between different applications along the processes, SAP uses the SAP One Domain Model (ODM).  This is a coherent data model with common semantics used to exchange data between applications of the Intelligent Enterprise Suite and its ecosystem.

ODM is released via API Business Hub which provides a visual presentation of the ODM between business objects each other and their types. The ODM is structured by domains. Each domain captures the essence of a certain area of business and contains different types like aspects, codes, entities and enums. Each domain can also have subdomains.

The following picture shows the graphical view of the ODM. This graphical view provides an overview of connected business objects and shows how they are connected each other. With release v2.1, SAP customers can use the integrated filtering function for domains and their types. The following picture shows the root entity BusinessPartner which has been released with version 2.1.


Filtering function of domains


In this graphical view it is possible to see all relations between BusinessPartner to other entities and other domain types like aspect, codes etc. This release of ODM provides an integrated filtering function for each domain type. It is possible to filter by the following types: Entities, Aspects, Codes, Types and Enums.


Business Partner

For example, by selecting Entities in the filter functionality, it is possible to see the relationships from the root object BusinessPartner to other related root objects. This feature gives customers the possibility to simplify the graphical view and display the relations between relevant domain types.

As mentioned above SAP One Domain Model supports now the object BusinessPartner in the Lead to Cash and Source to Pay process via MDI.

With the release 2.1. we enabled ODM BusinessPartner which describes an organization or person in which companies have a business interest. BusinessPartner is defined as ODM object and can be transmitted from/to MDI. Via MDI it can be shared and synchronized in the integrated Intelligent Suite and will be used as Customer within the Lead to Cash and Supplier in the Source to Pay processes.

You can  get a more detailed look into these processes on the API Business Hub page for SAP’s reference business processes.

Below you can see the SAP One Domain Model for BusinessPartner released on the SAP API Business Hub (click on “Explorers”, “SAP One Domain Model”), which provides a visual documentation of all business entities and their relationships to each other.

You can also find an official documentation where you can get more insights into SAP One Domain Model. Have fun in checking out the business objects of the SAP One Domain Model on the SAP API Business Hub.

      Hi Meltem Kahraman,

      what version of the ODM you are showing? Just asking, because in the current public available one on API Business Hub, entities like BusinessPartnerRelationShip or BusinessPartnerHierarchyNode are not shown. On your screenshot above these are available.

      Maybe it would be a good idea to display the version of the ODM in the ODM explorer (and maybe an option to switch versions would be  good to + a diff mode to display differences between the versions).

      Best Regards,
