The "save view status" on Creo Parametric, allow users to hide componentes on the assembly, and they stay allways hidden even if you click on "unhide all". This is very helpfull when we have skeletons or reference parts that we need but don't want to see.
I am having problems when I import a pvz to illustrate, because I work with very large assemblys and the parts that were hidden in Creo Parametric start showing up, and I cannot find a way to hide and save them.
If these are parts that don't need to be in the sBOM then I would suggest going to structure edit and remove them from the sBOM altogether.
If you do still need them in the sBOM then you could try unloading them from the sBOM, this would stop them becoming visible again when you hit Unhide All. You could even create a selection set with all the hidden parts to make it easy to control their visibility in the future.
