With "Edit levels" is possible to choose,what to see in list and what hide.
Even pc, after unpacking.
If using Teamcenter, you can edit the properties on that component, at the assembly level, and check the box that says it is reference only. If running native, you can set the attribute(s) PLIST_IGNORE_MEMBER and PLIST_IGNORE_SUBASSEMBLY with any value.
Here are the steps
Make the component as displayed part which you do not want to be listed in the Parts List. Under properties of component will find the attributes PLIST_IGNORE_MEMBER and PLIST_IGNORE_SUBASSEMBLY.
Switch to drawing at assembly level, you will not able to see the component in the parts list and balloons gets updated automatically with respect to the updated parts list.
Hope this will help!
