I don't know about TC but in drafting, this would be te way to tell NX not to call it in the part list.
I assume that ruud_vandenbrand answer was about the same.
note.:any value apply to those attribute will make them active, so you have to delete the attribute to get them back into their original state
In Teamcenter Structure Manager under the View Tab there is "Show Suppressed Occurrences"
This will hide all the Nx supressed parts , a Bom can then be exported from this and it will exclude all the Nx supressed parts, Alternatively you can do it with arrangements set up and managed in side nx, But then again in structure manager you can toggle on and off the different arrangements with the Yellow blocked arrangements icon inside the structure manager application in Teamcenter.
