Differences to Expect

This section lists certain differences that you may encounter when working with your imported ERwin model in PowerDesigner.

Why do I see errors in Check Model when my ERwin model was clean? PowerDesigner performs stricter checks than ERwin. For example, duplicate objects are not permitted in PowerDesigner, and the existence of orphaned items will generate a warning.

Why do some of my object symbols appear with numeric suffixes? If an object is required to appear more than once in a diagram (for, example, to improve readability), PowerDesigner will create a graphical synonym to represent it. Thus, if the table "Purchase" is displayed twice in a diagram, the two symbols will be labeled as "Purchase: 1" and "Purchase: 2".
