Is there still a Product Structure Explorer in Windchill 10.2

Hi,

I would like t know if there is still a way to create a bom manually by using a Product Structure Explorer in Windchill version 10.2 ?

Is there a way to feed this with info comming from Excel ? This I am asking because we will abandon the OSD drafting and for the rarely new 2D drawings we would create the bom manually.

Regards,

Bernard
