Synchronization
You can synchronize physical data objects when their sources change. When you synchronize a physical data object, the Developer tool reimports the object metadata from the source you select.
You can synchronize all physical data objects. When you synchronize relational data objects or customized data objects, you can retain or overwrite the key relationships you define in the Developer tool.
You can configure a customized data object to be synchronized when its sources change. For example, a customized data object uses a relational data object as a source, and you add a column to the relational data object. The Developer tool adds the column to the customized data object. To synchronize a customized data object when its sources change, select the Synchronize input and output option in the Overview properties of the customized data object.
To synchronize any physical data object, right-click the object in the Object Explorer view, and select Synchronize.
