Engineering System Design

Hi everyone,

I'm encountering a unexpected behavior in my model and would appreciate your insights. 

Here’s the setup:

• I'm working with Rhapsody 9.0.1.
• interface_A defines Operation_A
• interface_B defines Operation_B and has a generalization dependency to Interface_A
• class_4 contains port_0

The issue: 

• When I assign Interface_B as a provided interface to port_0, both Interface_B and its parent Interface_A are automatically included.
• However, when I assign Interface_B as a required interface, only Interface_B appears, Interface_A is not shown. which is what I would have expected.

Is this the expected behavior? Shouldn’t the generalization cause both interfaces to appear in both directions, or is there a specific modeling rule or tool configuration that explains this?

Thanks in advance for your help!
