Custom SAP Development
ABAP, Fiori/UI5 and BTP extensions built with clean core principles. Code that respects SAP standards, passes upgrades without conflicts and improves user experience.
Powered by ARIA, our AI assistant that analyzes custom code, detects obsolescences and recommends optimized development patterns.
Problems we solve
These are the most common challenges we find in our clients SAP landscapes.
Development that breaks standards
Direct Z modifications to SAP core that prevent updates, generate support package errors and create impossible-to-maintain long-term dependencies.
Obsolete interfaces nobody uses
Dynpros and classic transactions that users avoid due to complexity, reducing productivity and generating continuous manual entry errors.
No cloud strategy for extensions
All custom development inside the core complicates S/4HANA migration. Without BTP, every extension is accumulated technical debt growing with each sprint.
Slow and inefficient reports
ALVs built without CDS Views or HANA optimization that take minutes to execute and block critical monthly closing processes.
Non-existent technical documentation
Custom code without specs, without unit tests and without comments. When the original developer leaves, nobody understands the logic.
Outdated forms and outputs
Smart Forms and SAPscript that do not comply with CFDI 4.0, are not responsive and require manual intervention for every layout change.
Development capabilities
ABAP Clean Code Development
ABAP code with OO patterns, automated unit testing with ABAP Unit and SAP standard naming conventions.
Fiori/UI5 Applications
Responsive apps with Fiori Elements and freestyle that modernize user experience on any device.
SAP BTP Extensions
Cloud-native extensions with CAP Model and RAP that keep the core clean and upgrade-ready.
Upgradability Preservation
Enhancement spots, BAdIs, implicit/explicit exits: all development respects the SAP upgrade path.
Clean Core Migration
Legacy development migration to clean core architecture with Custom Code Migration analysis.
CDS Views & AMDP
High-performance reporting with CDS Views, AMDP and native HANA optimization.
Workflows & Approvals
Custom approval flows with SAP Workflow, Fiori My Inbox and automatic notifications.
Adobe Forms & Smart Forms
Professional print forms compatible with CFDI 4.0 and automatic email distribution.
Transport Management
Rigorous DEV-QAS-PRD transport management with naming conventions and documented cutover plan.
ABAP Performance Tuning
ABAP code analysis and optimization with ST05, SAT and HANA SQL trace for optimal response times.
ARIA
Artificial Intelligence at the service of SAP development
ARIA analyzes existing custom code, automatically identifies obsolescences, suggests clean core refactoring patterns and generates technical documentation. Reduces code analysis time by 60% and detects upgrade risks before they become problems.
Development methodology
Landscape Analysis
We evaluate the SAP landscape, existing developments with Custom Code Migration and define target architecture with prioritized recommendations.
Technical Design
Detailed technical specification with UML diagrams, core vs. side-by-side decision, data model and comprehensive testing plan.
Iterative Development
Coding in DEV with 2-week sprints, cross code review, unit testing and functional validation per iteration.
Comprehensive Testing
Unit tests, integration tests, regression testing and UAT with key users documented in test scripts.
Transport & Go-Live
QAS to PRD transport with cutover plan, post-deploy validation and 30-day hypercare support.
Post-Deploy Support
Active monitoring, defect correction, complete technical documentation and knowledge transfer to the internal team.

Deliverables
Industries we serve
Frequently asked questions
Can you audit our existing custom code?
Yes. We use SAP Custom Code Migration to analyze all Z code, identify obsolescences, dead code and upgrade risks. We deliver a report with a remediation plan prioritized by impact and effort.
Do you develop on S/4HANA and ECC?
Yes. For ECC, we develop with future migration in mind using clean core. For S/4HANA, we use RAP, CDS Views and native extensibility model to guarantee upgradability.
What guarantee do you offer on development?
All development includes unit testing, complete technical documentation and 30-day post-deploy support. Code is 100% client-owned with knowledge transfer included.
How do you handle transports between environments?
We follow the standard DEV > QAS > PRD process with rigorous transport management, naming conventions and documented cutover plan. Each transport includes functional validation.
What is the difference between in-core and side-by-side development?
In-core uses enhancement spots and BAdIs within SAP. Side-by-side extends functionality via BTP without touching the core. We recommend side-by-side for new logic and complex extensions.
Can you develop offline Fiori apps?
Yes. We develop Fiori apps with offline capability using SAP Mobile Services and automatic synchronization when the device regains connectivity. Ideal for plants and warehouses.
