Creating a qualifier
You can create a Qualifier for each end of an Association.
To create a qualifier on an association:
1. Open the Association's Property Pages.
2. Click the Start Role tab or End Role tab as appropriate.
3. In the When Qualified By box, type the name of the Qualifier you want to create.
Modeler creates the Qualifier in the model.
Note that if you delete the text in the When Qualified By box, Modeler deletes the Qualifier.
