SAP Custom Application Development

Build. Innovate without compromise.

Build. Innovate without compromise.

Every organization is unique — and so are its challenges. Standard SAP functionality can fall short when it comes to unique business needs. But core solution modifications create technical debt, complex upgrades, and rising costs.

SAP Business Technology Platform (SAP BTP) is the platform of choice to implement extensions for decoupled scenarios, where On-Stack development does not fit. In this way, your ERP core also stays clean, stable and upgrade-safe.

  • Stay clean: Protect your SAP Clean Core so upgrades stay predictable, and your landscape remains lean.
  • Extend smart: Build side-by-side apps on SAP BTP that add real business value without touching the digital core.
  • Innovate fast: Combine pro-code and low-/no-code tools to deliver new solutions in weeks, not months.
  • Connect everything: Integrate AI, analytics, and automation into your processes to unlock new insights and efficiencies.

"The boundary conditions to decide, which technology fits best are numerous nowadays. The question to go for the SAP BTP (e.g. CAP / ABAP Cloud) or alternatively pick Developer (or even Key User) Extensibility directly on your system must be a well-conceived decision and not influenced by personal preferences. A fully clean-core-compliant extension can be achieved in either way, if you play by the rules!"
