Compare Objects Across Systems

Compare the same ABAP object side-by-side between two connected SAP systems — useful for verifying transports, investigating system-specific behaviour, or checking what's in production before a deployment.

Prerequisites

• At least 2 SAP systems connected in VS Code
• The object must exist in both systems

How to Compare

1. Open or locate the ABAP object in the Explorer or editor.
2. Trigger the command using one of:
   • Explorer: right-click the file → Compare With another SAP System
   • Editor: right-click inside the file → Compare With another SAP System
   • Command Palette (Ctrl+Shift+P): ABAP FS: Compare With another SAP System
3. Select the target system from the quick pick list (shows only connected systems).
4. VS Code opens a diff view titled OBJECT_NAME: DEV100 ↔ QA100.

Notes

• The diff opens as a standard VS Code side-by-side comparison — all editor shortcuts (e.g. F7/Shift+F7 to jump between changes) work as normal.
• Path differences between SAP versions are handled automatically (Source Code Library for newer systems, Source Library for older ones).
• If the object does not exist in the target system, an error is shown.
