Simplifier On-Premise Modernization

Modernizing SAP On-Premise – with Clean Core & Side-by-Side

Stay flexible in any SAP constellation – now and in the future

Show-stopper SAP On-Premise?

Certainly not! Because whether you use SAP ECC or SAP S/4HANA on-premise: With the Simplifier digitalization platform, your SAP core remains stable at all times. Everything that brings innovation is simply implemented outside.

Typical customer view:

Uncertainty & pressure to make decisions

"Do we have to switch to SAP RISE or S/4 Cloud now?"

Fear of compliance and security risks when continuing operations

Budgets flow into support & licenses – not into visible improvements

Departments wait, IT secures operations instead of innovation

Core message:
Modernization ≠ Migration. With side-by-side, you secure investments in new processes – regardless of whether you later switch to the cloud or another system environment.

Advantages of Simplifier for SAP on-premise modernization

Clean Core & Side-by-Side: Modernize where it creates value – and keep the SAP core stable and updateable.

Clean Core & Upgrade Security

No risky interventions in the core. Extensions, UX, workflows and integrations run side-by-side – so updates can be planned and the core remains SAP-compliant.

- Less release stress
- Lower risk of obsolescence
- Architecture remains manageable

Reusable investments

Processes and applications that you build side-by-side today remain usable – even if the SAP operating mode (on-prem → hybrid → cloud) changes later.

Protection against re-investment
Portability of processes
Freedom of choice

Innovation today, decision tomorrow

Bring modern UX, automation and AI into your landscape – without a big-bang transformation and without vendor lock-in due to short-term pressure.

- Faster implementation
- More departmental benefits
- Reduced external dependencies

What exactly does side-by-side mean?

With side-by-side development, SAP systems are expanded in a future-proof and flexible manner without jeopardizing the maintainability of the core. Typical scenarios for this are, for example

the development of Fiori apps that access SAP data but require special logic
the integration of external data (e.g. from Salesforce or weather data) with SAP processes
the creation of mobile apps for warehouse workers.

In side-by-side development (definition in SAP Learning), the extension is not permanently extension is not permanently integrated into the ABAP code of the SAP ERP, but is an independent application. Data is exchanged between the extension (on the BTP) and the SAP core via standardized interfaces (REST APIs, OData). As the application runs externally, updates and enhancements can be carried out without disrupting the operation of the core system or forcing complex regression tests in the ERP.

Typical dead ends that you should avoid:

ABAP in-house developments that complicate upgrades

Single-point solutions that create silos and shadow IT

"Wait and see" strategy with innovation backlog

Complexity build-up due to unrelated individual solutions

Best practices for EVERY SAP strategy

SAERTEX – Modern AI strategy side-by-side

AI & knowledge and process support (EEV) independent of the SAP release: controlled, integrable, scalable.

Takeaway:

AI is not a question of “ECC vs. S/4” – but of architecture. Side-by-side makes innovation immediately usable without burdening the SAP core.

What is it all about?

SAERTEX shows that AI innovation also works with SAP On-Premise – if the architecture is designed side-by-side. Data from M365, APIs and third-party systems are brought together in a modern data and integration layer.

What Simplifier delivers here:

UI/UX layer for user groups (web & mobile)
Process and integration logic between data sources & AI
Option for on-prem AI (e.g. Mistral) and cloud models (e.g. ChatGPT)

Mann & Schröder – Modernizing S/4HANA On-Premise

Implement SAP-related processes faster – without ABAP bottlenecks, without external dependencies, with a clear platform strategy.

Takeaway:

Side-by-side development makes S/4HANA On-Premise agile – without overloading the core.

What is it all about?

Mann & Schröder Cosmetics operates SAP S/4HANA as the center of a complex IT infrastructure (including MES, Autostore, driverless transport systems). Despite automation, the internal team was reaching its limits. The high cost of customization and a lack of ABAP expertise led to slow processes and frustration in the specialist departments.

What Simplifier delivers:

After experience with another low-code platform, Mann & Schröder made a conscious decision to consolidate with Simplifier: SAP-related processes via Simplifier, Microsoft-related applications via Power Platform.

Reduction of external dependencies
More implementation speed
Better synchronization of IT & specialist departments
Reliable partner “Made in Germany”

ElringKlinger – “Hybrid” is the reality of transformation

Modernize as SAP changes: unified process & UX layer across on-prem, private cloud and cloud components.

Takeaway:

Transformation is a process – not a “deadline”. Side-by-side keeps you capable of acting.

What is it all about?

ElringKlinger shows a typical transformation path: EWM is already in the cloud, while other parts of the landscape continue to run on-premise. This is precisely why a stable modernization level is needed that keeps integrations, processes and user experience consistent. This minimizes the project risk and enables continuous value creation.

What Simplifier delivers:

With Simplifier, processes, apps and automations can easily be set up side-by-side. Above all, everything can be reused later if, for example, operating models or SAP components change.

ANWR – With side-by-side extensions to the “Clean C4C”

OData, events, HTML mashups – without upgrade risk due to in-house developments in the product core.

Takeaway:

Anyone who expands the SAP toolchain with the user-friendly Simplifier system environment remains independent and flexible.

What is it all about?

The ANWR Group is one of the most successful retail cooperations in Europe and uses SAP C4C (SAP Cloud for Customer). The cloud-based CRM solution offers real-time data and high mobility for sales, marketing and service. “Clean C4C” means keeping the SAP CRM system as close as possible to the provider’s standard. However, customizations are often necessary that cannot be optimally mapped using standard functions due to their individuality.

What Simplifier delivers:

With Simplifier, the data could be retrieved from the SAP Sales & Service Cloud via OData interfaces, changed on a low-code basis without complex programming work and written back again. In the Simplifier Process Designer, the linking of connector calls could be displayed visually so that nobody has to write Java Script code.
