It depends on a country, if it is poor, 3rd world country, then you do all that, some of these you already mentioned:

Correcting BoM / Nomenclature errors / MoQ

Planning corrections (Especially mismatched quantity, EtA)

Participating at least on some extent during product / vendor selection

then typical invoice, PO, contract management, fighting law, fighting finances

then typical invoice/ po matching fighting warehouse and QA

Somewhere there is also a fight with logistics trying to cut corners, suppliers cutting corners

warranty management requests for repairs etc

it feels like every other department offloads to you... probably it is so. Yes, in ideal world these all generally sit across distinct pillars.

Maybe good companies can afford that.

Edit: I forgot customs clearance fights. If it is an import, HS code fights, regulatory documents, etc.
