3. This is a quick guide to assist consultant in expediting the installation and implementation process. If you wish to dig deeper into this topic, please refer to the Application help of PLMSI 3.0.
1. Integration Between Siemens Teamcenter and SAP S/4HANA
An integration between Siemens Teamcenter and SAP S/4HANA helps you to streamline your product development processes in a diverse system landscape. It helps to integrate your existing Siemens Teamcenter data management systems flexibly and brings design data into the Product Lifecycle Management in SAP early on.
The integration enables the smooth exchange of product-relevant data as part of bi-directional process integration. An aligned Meta Domain Model provides standardized interfaces to simplify the integration. Relevant aspects of the configuration and foundational master data (for example, classification, units of measurement, pick lists, and so on) are exchanged between the Siemens Teamcenter system and the SAP system. SAP master data, like materials and bills of materials, and SAP documents are automatically created and triggered by data transfer from the external PLM system.
Furthermore, the integration enables you to monitor and troubleshoot the data transfer at a technical and business level. It also adapts data mapping without coding.
2. PLM System Integration Solution Architecture and Supported Business Processes
2.1 PLM System Integration Solution Architecture:
This section outlines the overall solution architecture of PLM system integration (PLMSI) for the integration between SAP S/4HANA and an external PLM system.
Note PLM system integration is designed to support 1:1 system integration between one SAP system and one external PLM system.
Overall Solution Architecture - SAP S/4HANA The integration connects the SAP S/4HANA software portfolio with an external PLM system to address the entire product lifecycle from Design-to-Operate ideation until end of life. A joint installation and integration of SAP S/4HANA with an external PLM system supports various scenarios based on customer business requirements. The integration provides a strong foundation for product engineering and manufacturing-centric scenarios. You can transfer configurable or non-configurable plant-specific information (material master, BOM, routing) with or without object dependency to the SAP system. The two systems can communicate through a common Meta Domain Model (see next section) using a REST protocol and JSON for interchange.
2.2 Supported Business Processes
An integration between SAP S/4HANA and an integrated PLM system supports a variety of business processes. The integration supports the end-to-end business processes Make-to-Stock and Configure-to-Order.
The integration supports the end-to-end business processes Make-to-Stock and Configure-to-Order:
- New Product Development & Introduction (NPDI)
- Major Change (Engineering Change Management and Manufacturing Change Management)
- Minor Change (Engineering Change Management and Manufacturing Change Management)
Compared to the Major Change scenario, New Product Development & Introduction (NPDI) supports additional steps in the early development phase (such as developing high-level product structures, requirements, and others), depending on the corresponding roles and authorizations.
3. Data Model
An aligned Meta Domain Model between the SAP system and Siemens Teamcenter is foundational to the integration as an intermediate layer. It’s an abstraction of the data that needs to be exchanged between Siemens Teamcenter and SAP S/4HANA.
The Meta Domain Model sets the foundation for traceability, federation, and linkage across system boundaries, focusing on processes and data transfer from product development to the SAP system. These are its main features:
- Exchange of material masters between the SAP system and Siemens Teamcenter based on business semantics
- • Exchange of material classification information to enable a consistent information flow • Creation of document info records in the SAP system
- Transfer of bill of materials to the SAP system
- • Engineering change triggered in Siemens Teamcenter
- Engineering change triggered in the SAP system
- • Data federation for product version, structure version, change object, and document version data within Siemens Teamcenter
3.1 Meta Domain Model - Core Concept
The Meta Domain Model (DM) is a data model that helps to reduce the level of complexity when integrating an SAP system with an external PLM system. To ensure data consistency and quality for subsequent processes, the integration offers a consistent data logic, enabling you to configure your processes without interrupting them. It translates and standardizes the integration between the two systems and provides a stable and aligned process and data model. This is the foundation to establish a reliable and resilient business process.

4. Data Federation
Data federation provides detailed insights into different business entities in the respective application without the need to log on to different applications.
The following data federation options are available for different business entities:
- Product version (bidirectional)
- Customer Order Item (unidirectional – SAP data display in an external PLM system)
- Document version (unidirectional – SAP data display in an external PLM system)
- Document version file (unidirectional – SAP data display in an external PLM system)
- Change object (bidirectional) includes change notice, change request, and problem report for both change master and change record
- Structure Version (bidirectional)
5. Installation Flow for PLM System Integration for SAP S/4HANA
Carry out the steps in the order shown below to ensure proper data flow, authorization setup, and security. SAP recommend that you save your entries frequently.
