SEGW (Service Gateway Builder) is a transaction code used to create ODATA services in SAP NetWeaver Gateway. It lets you define models, entities, and implement CRUD operations using a UI-based interface.

Steps to Create an ODATA Project in SEGW

Step 1: Open Transaction SEGW

• Go to the SAP GUI command field.
• Type SEGW and press Enter.

You’ll be taken to the Gateway Service Builder screen.

Step 2: Create a New Project

•   Click the Create Project icon (white sheet of paper).
• A popup will appear asking for:
  • Project Name (e.g., ZSALES_ODATA)
  • Description (e.g., “Sales Header and Items OData Service”)
  • Package (use $TMP for local/temporary if you’re just testing)
  • Transport Request (if using a package)

Hit Continue (✓).
