Custom integrations

Custom SAP integration for the systems standard connectors do not cover.

Relay handles SAP interface development and SAP API integration when the real work sits in custom data models, business logic, transformations, surrounding applications and production requirements.

Typical systems

Legacy, operational and custom applications around SAP.

Custom integration work often starts where SAP must interact with service platforms, legacy systems, custom software, GIS, databases or file-based exchange patterns.

Typical problem

The business flow spans different data models and ownership lines.

Objects, identifiers and process states rarely align cleanly across the applications involved. That is where mapping, validation and orchestration matter.

Typical delivery need

Keep what already works. Engineer what does not.

Relay complements existing middleware, APIs and interface patterns instead of forcing a new platform decision just to solve one difficult process.

Integration scope

Custom integration work usually sits around SAP, not inside one packaged connector.

Relay helps when the flow crosses several systems and the difficult part lies in mapping, enrichment, sequencing, validation and operational ownership.

SAP core processes
SAP master & transactional data
SAP custom logic
Relay delivery scope
  • Cross-system mapping
  • Transformation & enrichment
  • Business rules & orchestration
  • Monitoring & support
Service / CRM platforms
SQL, files & legacy systems
Custom applications & GIS

The objective is an operable business flow across the landscape, not custom code for its own sake.

When custom makes sense

Use standard connectivity where it works. Engineer the parts that do not.

Relay is not a reason to rebuild a standard interface. Custom integration becomes useful when the process depends on non-standard SAP structures, several systems, different data models, additional validation or business rules that a packaged connector does not cover.

The focus is the complete operational flow, not custom code for its own sake. Good custom integration work is targeted, structured and aligned to the business process that actually needs to run.

  • Custom SAP objects and business logic
  • Multi-system process orchestration
  • Databases, files and API-based integration patterns
  • Legacy or specialised systems that do not fit a packaged connector approach
What Relay delivers

Architecture fit, delivery ownership and production readiness.

Relay can complement existing middleware and interface patterns rather than forcing a new integration platform. The implementation approach is chosen around the customer landscape, SAP release, operational constraints and the flow that needs to work.

That can mean SAP-native interfaces, APIs, databases, file-based exchange, existing middleware or a combination of them - plus the testing, monitoring and documentation required to operate the result.

  • SAP S/4HANA and SAP ECC
  • CRM, service and other enterprise applications
  • Databases, legacy systems and custom software
  • GIS and specialised operational applications
FAQ

Questions buyers usually ask about custom integrations

Does “custom integrations” simply mean bespoke code?

Not necessarily. It means the end-to-end flow needs engineering beyond what a packaged connector provides. Often that includes selective custom logic, but always with the aim of keeping the solution as pragmatic and maintainable as possible.

Can Relay work with the middleware and interfaces we already use?

Yes. Relay is designed to fit the existing landscape. We can work through current middleware, APIs, files, databases or direct SAP interface patterns where appropriate.

What kinds of systems are usually in scope?

Typical examples include service platforms, CRM tools, legacy operational systems, bespoke applications, GIS, databases, files and specialised applications around the SAP core.

How do you keep a custom integration maintainable?

By limiting custom work to the parts that truly need it, documenting the flow, implementing monitoring and error handling, and designing the interfaces around clear ownership and operating processes.
