已知限制

Known limitations for external source objects, folder-level entities, and Solutions integration in Data Fabric / Data Service.

以下已知限制适用于来自外部来源的对象：

• A single entity cannot hold both locally stored fields and external fields. Locally stored data can be included in a Federated entity by referencing a native Data Fabric entity as a source. For more information, refer to Entity types.
• Data write-back for insert and update operations does not support external sources. A Federated entity is a read-only view, and write operations on it return an error.
• File data from external systems is not supported. A File field can be referenced from a Native source.
• Encrypted fields of a native entity cannot be referenced in a Federated entity. A field with Encrypt Data enabled in its Advanced options is not supported as a Native source field.

以下限制适用于文件夹级别的实体和 Solutions 集成：

• Inline entity creation during deploy or upgrade is not supported. Entities must be defined in the Solution package or already exist in the target folder.
• Deploy-time entity override is not supported. Entity overrides are available during debug and at runtime via Package Requirements.
• Overriding a related entity requires that the replacement maintains compatible schema relationships to avoid mismatch errors.
• When overriding a folder-scoped entity in the Query Multiple Entity Records activity, the replacement must have the same name as the original, because filter conditions reference fields by an entity-name prefix.
• Cross-scope relationships between tenant and folder entities are not supported.
• 无法将具有相同名称的两个实体添加到同一工作流中。
• Cross-folder reference entities cannot be packaged when you create a Solutions project in Orchestrator.
• 统一项目不支持文件夹级别的实体。
• Standalone VB Apps and RPA (UB) Apps do not support folder-level entities.
• Local Workspace does not support folder-scoped entities via Data Service connector activities. Folder scope is available in cloud workspaces only.
• Schema refresh for federated entities is not supported in legacy activities (Data Service classic package).
