You can use the drag and drop feature from the Browser to the diagram window and conversely to create replicas while using the ALT+SHIFT keys combination.
When you create a replica using the drag and drop feature, a specific icon (a rounded arrow within a circle) appears under the cursor.
You can also define the default behavior of a drag and drop action to directly create replicas.
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.

The replica appears in the active model or package and in the Browser under the appropriate node.

You can also create a replica by clicking the right mouse button while
dragging the target object and select the Replicate Here menu item from
the contextual menu.
Sub-object
You can also directly replicate a sub-object by dragging and dropping it in
replication
the Browser while pressing the ALT + SHIFT keys combination. A table
column, a class attribute or a class operation are sub-objects that you can
replicate using the drag and drop feature.
It can be very useful to replicate a sub-object independently of its parent
object (for example a column without the table that owns it) to create a
reference library, in which you can store columns, attributes or operations for
example that you regularly use. The replicated sub-objects can be modified
according to your needs, while preserving the link to their target object.

The following example illustrates a column (Column_1) in Table_1 that is replicated in Table_2:

When you save the referencing model you save the replicas and the replication objects it contains with the path of the target model in order to allow data synchronization between original objects and replicas.
PowerDesigner asks you to save the model containing the original object before you save the referencing model of the replica.
By default, when you replicate an object, all its attributes, collections and
sub-objects are also replicated, as you want a local copy of the original object
while preserving the link to it. Thus, all replica attributes, collections and
sub-objects are synchronized with those of the original object, except when
their name and code have been renamed to preserve uniqueness. All attributes
appear grayed-out in the replica property sheet, as they cannot be modified.
However, you may wish to desynchronize some of the attributes from those
of the original object to meet specific needs. Thus, every time you modify the
original object, the desynchronized attributes, collections or sub-objects will
not be modified. The desynchronized items are no longer grayed-out in the
property sheet and can be modified.
Sub-replication
You perform a sub-replication when you replicate an object that owns sub-
desynchronization
objects (a table that contains columns for example), as its sub-objects are also
replicated. These sub-objects also contain attributes, collections and sub-
objects that you can desynchronize.
PowerDesigner
&KDSWHU 0DQDJLQJ 2EMHFW 5HSOLFDWLRQV
Unlike replicas, for which you desynchronize attributes and collections directly in their respective page in the replication property sheet, the desynchronization of sub-replications occurs in its own property sheet named Sub-Replication property sheet that you open from the replication property sheet.
1 Double-click a replica to open its property sheet.
2 Select the Version Info tab to display the corresponding page.
3Click the Replication Properties button in the Replicated From groupbox.
The replication property sheet appears.
4 Click the tab in which you want to desynchronize items.

Double-click the sub-replication for which you want to desynchronize items to open the sub-replication property sheet, clear the check boxes that correspond to items you do not want to synchronize from the different tabs in the sub-replication property sheet and click OK.
7Click OK.
Next time you modify the original object, the desynchronized items will not be synchronized in the replica.
5HSOLFD V\QFKURQL]DWLRQ
When you perform changes on the original object, whatever the status of the original object model (opened or closed), the replica owns information from the original object and can fully display them.
However, replica synchronization can happen at different times depending on the referencing model status ; the general rule being that synchronization occurs as soon as possible when both the original object model and the referencing model are opened.

:KHQ WKH UHIHUHQFLQJ PRGHO LV FORVHG Replica synchronization occurs when you will open the referencing model.
In any case, both the referencing model and the original object model must be opened in the workspace of the same machine for the changes of the original object to be propagated to the replica.
