SAP vs other ERPs (quick comparison)

What are the SAP programming languages?

SAP uses several programming languages, but the primary and most important one is ABAP.

Main SAP Programming Languages

1. ABAP (Advanced Business Application Programming)

• Primary language of SAP
  
• Used for:
  
  • Custom reports
    
  • Enhancements & user exits
    
  • Interfaces
    
  • Forms (SmartForms, Adobe Forms)
    
  • SAP S/4HANA backend development
    
• Runs on the SAP NetWeaver / S/4HANA platform
  
   This is the must-learn language for traditional SAP development.

2. Java

• Used in:
  
  • SAP PI/PO (Process Integration / Orchestration)
    
  • SAP Hybris (Commerce Cloud)
    
  • Older SAP Portal applications
    
• Less common in modern S/4HANA core development

3. SAPUI5 / Fiori (JavaScript-based)

• Frontend development for SAP Fiori apps
  
• Built with:
  
  • JavaScript
    
  • HTML5
    
  • CSS
    
• Works with OData services from ABAP or CAP
  
   Very important for modern SAP UX

4. SQL / SAP HANA SQL

• Used for:
  
  • Data modeling
    
  • Performance optimization
    
  • CDS Views
    
  • Native HANA procedures
    
• Especially important in S/4HANA

5. CDS (Core Data Services)

• Data modeling language used with ABAP & HANA
  
• Defines:
  
  • Views
    
  • Annotations (UI, analytics)
    
• Key part of S/4HANA extensibility

6. SAP BTP Languages (Cloud Development)

For SAP Business Technology Platform (BTP):

• Java
  
• JavaScript / Node.js
  
• Python
  
• CAP (Cloud Application Programming Model)
