The Incremental Deployment Wizard analyzes the impact to the run-time application while you add objects to the application patch and the patch inherits the objects' dependencies. You can preview the impact on each application object to understand how the run-time instance of an object will change after you deploy the patch.
The preview lists the following types of impact for each application object:
Modify. A run-time instance of the object exists in the run-time application, and the Data Integration Service will replace the run-time instance with the design-time instance.
Affected. The wizard will fetch the object from the run-time application because its run-time dependencies will be modified. The Data Integration Service updates the affected object in the run-time application to use the modified dependencies, but the service does not replace the it.
Add. A run-time instance of the object does not exist in the run-time application, so the Data Integration Service will create a run-time instance of the object in the run-time application.
No Change. The object will not be modified, affected, or added to the run-time application.
