When you create a shortcut using the drag and drop feature, a specific icon (a rounded arrow within a square) appears under the cursor.
You can also define the default behavior of a drag and drop action to directly create shortcuts.
For more information on how to define the default behavior of a drag and drop action, see section Defining drag and drop options in chapter Using the PowerDesigner interface.

When you save the referencing model you save the shortcuts it contains with the path of the target model in order to allow data synchronization between target and referencing objects.
You must always save the target model before you save the referencing model.
In case you have external shortcuts between two models that have never been saved, you have to save one model, then the other and the first one for a last time in order to save both model file paths.

You cannot create a link between two shortcuts in the referencing model; but you can link a shortcut to an object belonging to the referencing model.
However, you can keep the links existing between two target objects in the referencing model. Unlike shortcut symbols, the shortcut of a link does not show a particular icon that identifies it.
&UHDWLQJ WKH VKRUWFXW RI D OLQN
In the target model, when two target objects are linked, you can keep this link and create a shortcut for the link.
ϖ7R FUHDWH WKH VKRUWFXW RI D OLQN
1Select both target objects and their link using the SHIFT key for multiselection.
2Press CTRL + SHIFT while you drag the symbols and their link to the desired model or package and release the mouse button.
The object shortcuts appear with their link.

When the target model is opened, you can change the target object of a shortcut.
Usually, you change the target object of a shortcut when the shortcut status indicates a Not Found attribute in the shortcut property sheet. A shortcut can have a Not Found status when the target model is opened but the target object of the shortcut cannot be found for the following reasons:
♦Target object was deleted
♦Target object was duplicated in another package, then deleted in the original package
♦Target model was saved under a new name
General Features Guide |

'HILQLQJ D VKRUWFXW
In such cases you can either:
♦Delete the shortcut if the target object no longer exists in the target model
♦Select a new target object if the previous target object was renamed or moved
When selecting a new target object the following rules must be observed:
♦The new target object cannot be the existing target object
♦The new target object must be of the same type as the previous one (for example an entity shortcut cannot target a data item)
♦The new target object must not be already targeted by another shortcut defined in the same package because two different shortcuts within the same package cannot target the same object

2Click the Change Target Object button in the bottom left corner of the shortcut property sheet.

When you perform changes on the target object, whatever the status of the target object model (opened or closed), the shortcut owns information from the target object and can fully display them.
However, shortcut synchronization can happen at different times depending on the referencing model status:
:KHQ WKH UHIHUHQFLQJ PRGHO LV RSHQHG |
Shortcut synchronization |
occurs instantly. |
|
:KHQ WKH UHIHUHQFLQJ PRGHO LV FORVHG |
Shortcut synchronization occurs |
when you will open the referencing model. |

In any case, both the referencing model and the target object model must be opened in the workspace of the same machine for the changes of the target object can be propagated to the shortcut.
