SAP's proprietary programming language for business applications. Used in enterprise resource planning and financial systems.
ABAP (Advanced Business Application Programming) is a high-level programming language created by SAP SE in the 1980s for developing applications within the SAP ERP ecosystem. Originally designed as a report-generation language called ABAP/4 (fourth-generation language), it evolved into a full application development platform powering the core business logic of SAP R/3, S/4HANA, and the broader SAP Business Suite. ABAP runs exclusively on the SAP NetWeaver Application Server, making it unique among enterprise languages in its tight coupling to a specific runtime environment.
The language supports both procedural programming and object-oriented paradigms (ABAP Objects), along with built-in SQL integration through Open SQL for database-agnostic queries. ABAP is used by hundreds of thousands of developers worldwide across industries including manufacturing, finance, healthcare, retail, and government, where SAP systems manage critical business processes like supply chain management, financial accounting, human resources, and materials planning. The ABAP Development Tools (ADT) in Eclipse provide the modern IDE experience, while the SAP GUI traditional workbench remains in wide use.
SAP's ABAP RESTful Application Programming Model (RAP) represents the modern development paradigm for building Fiori applications and OData services. With SAP's cloud strategy, ABAP has extended to the SAP Business Technology Platform, ensuring the language's relevance as enterprises migrate from on-premise to cloud deployments.
ABAP changes in SAP systems directly affect financial transactions, compliance reporting, and supply chain operations across global enterprises. A modified function module or BAPI can impact dozens of dependent processes.
Comparing ABAP code is critical during transport reviews in regulated industries where audit trails are mandatory. Teams must diff custom code against SAP standard programs to identify upgrade conflicts and ensure that modifications to posting logic or authorization checks are thoroughly validated.
UtraDiff diffs ABAP files using ABAP syntax highlighting, rendering keywords, data declarations, and SAP-specific statements in distinct colors. Side-by-side view aligns method definitions and form routines across panels. The whitespace ignore toggle handles Pretty Printer formatting differences common in SAP development.
Alt+Arrow navigation jumps between changed statements. Language-aware tokenization distinguishes SELECT query modifications from data declaration changes in enterprise business logic.
Supported extensions: .abap
