If compiler errors and warnings are enabled for display on the schematic (enabled on the Schematic - Compiler page of the Preferences dialog), an offending object will display a colored squiggle beneath it. Hovering over the object will display a pop-up hint that summarizes the violation. A notification is also displayed in the Messages panel in the following format:
Multiple harness types on harness <HarnessType1>, <HarnessType2>
HarnessType1andHarnessType2are the multiple Harness Types specified across the Signal Harness.
Recommendation for Resolution
Use the Details region of the Messages panel to quickly cross probe to the offending objects (Sheet Entries, Ports, Harness Connectors, Harness Entries) within the Signal Harness. Specify only one Harness Type across the Signal Harness:
Port - specify a Harness Type in the Properties section, on the General tab of the Properties panel (which presents all properties for the selected object).
Sheet Entry - specify a Harness Type in the Properties section of the Properties panel (which presents all properties for the selected object).
Harness Entry - specify a Harness Type in the Properties section of the Properties panel (which presents all properties for the selected object).
Object hints will only appear provided the Enable Connectivity Insight option is enabled on the System - Design Insight page of the Preferences dialog. Use the controls associated with the Object Hints entry in the Connectivity Insight Options region of the page to determine the launch style for such hints (Mouse Hover and/or Alt+Double Click).
