+## 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`
