## Multiversion Support

MDI enables applications to use different compatible versions of the SAP One Domain Model without disrupting integrations.

**How It Works**:
- Application A transmits data in version 3.0.0
- Application B receives data in version 2.1.1
- Works only between compatible versions (no breaking changes)

**Benefits**:
- Decouples development cycles of SAP and non-SAP applications
- Allows incremental upgrades
- Reduces implementation complexity

**Limitations**:
- Only works between versions without breaking changes (e.g., no field removals)
- BusinessPartner v3.3.0 and v2.1.1 have restricted multiversion support for address data

## ODM Entity Name Format

writePermissions use fully qualified ODM entity names:

```
sap.odm.{domain}.{subdomain}.{EntityName}
```

Examples:
- `sap.odm.finance.costobject.CostCenter`
- `sap.odm.businesspartner.BusinessPartner`
- `sap.odm.procurement.orgunit.PurchasingOrganization`
- `sap.odm.workforce.foundation.WorkforcePerson`
