You can merge the content of two PowerDesigner models or two resource files of the same type at any time.
Select Tools > Merge Models to open the Select Models to Merge dialog.
The current model is displayed in the
To field.
Select a model to merge in the From
list. Only models of the same type in the workspace are available for
merging.
Note: If you want to merge two PDMs, BPMs, OOMs or
XSMs, you have to select two models with the same target DBMS or
language.
[optional] Click the Options button to
open the Comparison Options dialog and specify which objects and properties you
want to include in the comparison and possible merging (see Excluding Objects and Properties from a Compare or Merge).
Click OK to open the Merge Models window, which displays the
objects contained within the models or resource files in a tree format, and
highlights the differences between them (see Selecting Merge Actions). You can apply a filter to simplify the list of
differences (see Filtering Objects and Changes During a Compare or Merge).
Selecting the merge actions that you want to perform, and then
click OK.
The Merge Models dialog box closes and the merge begins, with
messages displayed in the Output pane. A final message
informs you that the models were successfully merged.
Selecting Merge Actions
The Merge Models window displays the anticipated result of your proposed merge as a tree of objects, with check boxes to the left of each potential change to allow you to approve or reject it. The properties pane lists each of the properties of the selected object, and allows you to select or reject the values proposed in the To column. Select or deselect actions as appropriate and then click OK to perform the merge.
