```
**Response**:
```json
{"success":true,"service_definition_name":"ZSD_CUSTOMER","uri":"/sap/bc/adt/core/srvb/srvbdefinitions/zsd_customer","message":"Service definition ZSD_CUSTOMER created and activated successfully"}
```

## Complete Workflow Summary
```
1. CreateDomain (activate: false) × N
2. CreateDataElement (activate: false) × N
3. CreateTable - Root (activate: false)
4. CreateTable - Draft (activate: false)
5. CreateView - Interface (activate: false)
6. CreateView - Consumption (activate: false)
7. CreateBehaviorDefinition (activate: false)
8. CreateBehaviorImplementation (activate: false)
9. CreateMetadataExtension (activate: false)
10. ActivateObjectLow - Group activation of all objects
11. CreateServiceDefinition (activate: true)
```
## Important Notes
- **Always set activate: false** for steps 1-9
- **Group activation** ensures proper dependency resolution
- **Service definition** can be activated immediately (depends on already activated views)
- **Order matters**: Create in dependency order
- **Code checking**: When using low-level handlers, always check code before update
