	♦	Only identical objects
	♦	Only selected objects
	♦	Show only conflicts
	♦	Hide all preservations
Understanding	When you are performing a generation or a consolidation, you can use the
conflicts	"Show Only conflicts" filter.
	This filter displays conflicts between models with common origin such as
	local model and consolidated model or origin model and generated model.
	A merge conflict occurs when corresponding objects have been modified in
	both the origin and generated model or the local and Repository model. Such
	modifications can be a change in object properties, a change in a list of
	objects, a change in the order of a list or the deletion of an object.
	For more information on defining a merge filter, see the section
	Defining a comparison filter.
Understanding	When you are performing an intermodel generation, you can use the "Hide
preservations	All Preservations" filter.

This filter hides all differences associated with changes made in the model to be merged as well as all identical objects in order to show only changes made in the model on the left since last generation.

For each difference detected during the comparison process, a merge action is proposed for you to synchronize the model to be merged with the model on the left pane. In the model to be merged, when a merge action is proposed for an object in the tree view, a check box appears beside the object. The type of merge action is displayed under the form of an icon in the bottom right corner of the object.

Merge icons are composed of a symbol and a colour. Each of them has a specific meaning.

Moving an object from a package to another

'LIIHUHQFH	0HUJH DFWLRQ	,FRQ
Shortcut creation	Creates shortcut in target model
		(blue)

When you merge models in one of which you have moved an object from a package to another and modified its properties, the object appears in both packages of the model to be merged, in the object comparison part.

In the the following example, Entt_5 in Package 2 was modified and moved into Package 1:

,FRQ 'HVFULSWLRQ

One occurrence remains in the package on the left pane and the opposite icon is displayed at the bottom right corner of the object to indicate that the object properties were modified

The second occurrence appears grayed out in the package to be merged and the opposite icon is displayed at the bottom right corner of the object to indicate that the object was moved but does not yet exist in that location

You are invited to synchronize the models on the right and left panes by selecting both check boxes.

&KHFN ER[ V\QFKURQL]DWLRQ

When you select or clear a merge action check box for a moved object, the check box of the other occurrences are automatically selected or cleared.

PowerDesigner

When you move an object that is replaced with a shortcut, the merge action suggested is the move with no indication of shortcut replacement. The unique indication of the object replacement with a shortcut appears with the following icon in the model on the left pane of the Merge Models dialog box:

In the following example, Entt_2 in the main diagram was moved into

Package 2:

Move target object

When you merge models, move is not a suggested merge action for objects which are in different namespaces but have identical name. In that case creation or deletion of the object are proposed.

For more information on namespace in models, see section Managing the namespace in models in chapter Managing Models.

User permissions When a user does not have the appropriate rights and permissions in the

in the repository repository, merge actions appear with a grayed out check box and cannot be selected.

However, some actions can be applied to objects in packages on which the user does not have the required permission, in order to be consistent with a permitted action.

In the following example, the model on the left pane corresponds to the local model and the model on the right pane corresponds to the repository model. The user has a Read permission on Package 1 and a Write permission on Package 2.

		For generated models, the merge actions selected by default depend on the

When objects have different definitions, you can select a merge action to synchronize their definitions. PowerDesigner lets you define exactly which property you want to merge in the object definition.

You can double-click a property in the property comparison part to display differences between models.When a line is added the following symbol appears >>, when a line is deleted, the following symbol appears <<.

By default, the diverging properties are selected in the list:

When an object has been renamed or modified out of the PowerDesigner interface, the link with the corresponding object in the compared model is lost.

In such situation the comparison interface will display two disconnected objects in the model trees with object creation and deletion actions in each model.

The manual synchronization will let you rebuild equivalence between disconnected objects and refresh the object comparison part. This advanced feature supposes you are very familiar with the model contents.

For manual synchronization, you have to define the following parameters:

	From Object	Object on the left pane used as reference for manual

		can select another model or package from the dropdown listbox
	To Object	Object on the right pane to be synchronized, you can use the
	To Object
		Properties tool to better identify object

Manual synchronization lets you perform the following operations:

♦Synchronize moved or disconnected objects. You can use the Parent box to select the parent package corresponding to the package on the left pane.

♦De-synchronize objects that share common properties and are naturally related in the comparison process. You can select <NONE> or another object from the Object dropdown listbox in order to break the relation between objects.

The tree view of the model to be merged is automatically updated after you validate a manual synchronization.

The Manual Synchronization dialog box appears. According to the merge action proposed, the From or the To box is editable.

3Select a new package or model in the Parent dropdown listbox.

4Select the object that will become the reference for synchronization in the Object dropdown listbox.

5Click OK.

The selected items are synchronized and the tree view of the model to be merged is updated in order to show the impact of the manual synchronization.
