After careful review, it has been determined that this defect will not be fixed. Please reference the following link: CA PPM Defect Resolution Policy for more information.
For custom attributes: Create the attribute on the Investment object and then the data will show up properly in the list views for the subobject.
For out of the box attributes: The only workaround would be to create a custom attribute on the investment object and link that to the Idea and Project Type lookup (or applicable lookup). As long as the attribute ID is different then other objects, this issue should then not occur when you create a virtual attribute on the team object.
- Note: If creating a custom attribute, data from the out of the box attribute does not get automatically populated to this new attribute. Additionally, any portlets or views using this field would also have to be updated to replace the old attribute(s) with the newly created attributes.
