Item Master and Commodity/UNSPSC Codes

[larondet]

I'm using F4101Z1 Item Master Revision to upload Items to the Item Master. I would like to be able to assign a Commodity and UNSPSC Code from my Commodity Code Structure and associated UNSPSC Codes. I've looked through all the fields but can't find the field that links items to the commodity structure. Am I missing something? Please let me know if you require anything further to assess this issue. It also occurred to me that possibly there is a global update to assign codes?

What I'm trying to avoid is going into each Item (of which we have thousands) to assign a commodity and UNSPSC code.

Any help would be appreciated.

Thanks to all who respond.
