Is the SAP Standart not enough for you?

Individual solutions based on state-of-the-art SAP technologies

Is the SAP standard not sufficient for you? Then extend it the right way. With a clear architecture, modern SAP technologies, and a consistent clean-core strategy, we create stable, upgradeable, and future-proof solutions.

As an experienced SAP consulting and development company, .XPN delivers tailored SAP solutions precisely aligned with the needs of mid-sized businesses. Our experts guide you from concept to go-live – structured, efficient, and with a strong architectural focus.

Individual requirements demand individual solutions – but without technical compromises in the SAP core.

Keep the Core clean
Strategy & Philosophy

“Keep the Core Clean” is more than a technical principle – it is a strategic development approach clearly recommended by SAP.

Objective and Principle
Objective and
Principle

The objective is to keep the SAP core stable, upgradeable, and low-maintenance, while implementing individual extensions flexibly via upstream layers.

Core modifications lead in the long term to increased maintenance efforts, more complex upgrades, and rising operating costs. The clean-core approach prevents exactly this – through a clear separation of standard and custom extensions.

.XPN consistently applies this approach, creating modern, scalable solutions with maximum operational reliability and flexibility. Thanks to SAP-native frameworks and development environments – from ABAP RAP and SAP CAP to SAP BTP – innovative applications can be developed and seamlessly integrated into existing system landscapes without modifying the core.

Modernization & Migration to BTP

.XPN supports companies in systematically transferring existing applications from the classic SAP system to the SAP Business Technology Platform (BTP).

Through the targeted use of the ABAP Environment on BTP (Steampunk) , migration is efficient and future-proof – without sacrificing established development standards or existing expertise.

Steampunk – the ABAP Environment on BTP

The ABAP Environment offers numerous advantages for companies that want to continue leveraging existing development resources while moving toward a future-proof, cloud-based architecture.

The advantages of ABAP Environment on BTP
  • Utilization of existing ABAP expertise
    Companies can continue using their existing know-how and developer teams without introducing new programming languages or platforms. This enables a smooth transition to the cloud using familiar tools.
  • Extension of SAP systems in the ‘Clean Core’ approach
    With ABAP on BTP, extensions can be developed outside the SAP S/4HANA core – fully aligned with the ‘Keep the Core Clean’ principle. This enhances upgradeability and maintainability.
  • Development of standalone cloud applications
    In addition to extending existing systems, entirely new standalone applications can be developed – cloud-based, scalable, and independent of the on-premise system.
  • Access to modern technologies & Services
    Through integration into the SAP Business Technology Platform, developers gain access to additional services such as SAP Integration Suite, SAP Event Mesh, SAP AI Core, SAP Build Workzone, and many more – directly combinable with ABAP applications.
  • Clean architecture & modern development models
    The ABAP Environment uses the ABAP RESTful Application Programming Model (RAP) and is based on modern cloud principles, resulting in future-proof, streamlined, and maintainable applications.
  • Full lifecycle integration
    Deployment, transport management, and operations are seamlessly integrated. With Git integration, change management, and DevOps capabilities, ABAP projects can be professionally managed – including in agile teams.
  • Multi-tenant capable & client-independent
    ABAP on BTP is client-independent and particularly suited for scenarios where multiple customers or business units need parallel access to the same solution.

Architectural Expertise in Implementation

Technology alone is not enough. The decisive factor is a sound architectural decision.

.XPN analyzes existing system landscapes, evaluates extension options, and develops clear architectural guidelines:
  • What belongs in the core?
  • What is implemented side-by-side?
  • Which services are integrated?
  • How does the system remain upgradeable in the long term?
