Thank you Ganesh, but I "need" that the supression command be undestood by TC not to use a different tool to not show components in structure manager because it would take us more time and as not visual as supression command it may lead to mistakes.
Yes, you'll also notice that the setting in Structure Manager affects things like plmxml export, and utilities like BOMWriter. If Show Suppressed Occurrences is toggled on in SM, then running BOMWriter outside of Teamcenter (on the same workstation) will honor that setting.
Ganesh, your advise of using REFERENCE_COMPONENT is also useful, I think I can use it for manage some assemblies that are manufactured outside or company and we dont "care" about structure. Thank you!
