SAP Technical Architecture

Sound foundations for SAP programs

Technical architecture guidance for SAP S/4HANA, BTP, integration, and extensibility.

Service overview

Technical architecture guidance for SAP S/4HANA programs: extension strategy, integration design, development standards and the governance needed to keep them in place.

Engagements typically start with a review of the current landscape and delivery practices, then produce a blueprint that names the target patterns for each type of requirement.

Standards are written so they can be enforced through ATC and code review rather than depending on individual reviewers.

Problems this service addresses

  • Unstable integrations between SAP and surrounding systems
  • No agreed extension or development standard across teams

  • Clean core compliance issues appearing across multiple projects
  • Inconsistent quality between internal and partner development

  • SAP technical leads
  • Consulting firms running multi-team SAP delivery

Engagement approach

  1. 1

    Discovery and access review

    Short qualification call, confirmation of scope, systems, releases and the technical access required.

  2. 2

    Technical assessment

    Hands-on analysis in your system using ADT, ATC, trace and analysis tools relevant to the scope.

  3. 3

    Findings and prioritization

    Findings written up with severity, effort indication and a prioritized backlog agreed with your team.

  4. 4

    Implementation or remediation

    Agreed changes implemented in transports, with code review against your standards.

  5. 5

    Testing and knowledge transfer

    Testing evidence handed over plus a walkthrough session so your team can continue the work.

Expected outcomes

  • Strengthens technical governance across teams
  • Improves maintainability of new and existing developments
  • Supports upgrade readiness through agreed extension patterns
  • Helps identify integration designs that create operational risk

Outcomes depend on system landscape, code base and available access — no fixed results are guaranteed.
