Removing a single item from a relationship

获得 Production Mapping 许可后可用。

As needed, you can remove a related feature or table record from a related feature. This can occur when you need to change the table record or feature with which another feature is related. For instance, you may need to remove a relationship between a feature and a table record because the table record is related to a different feature. To create a relationship between a different feature and the table record, the relationship must be removed between the current feature and table record.

2. 如有必要，可在地图中加载数据。
