How do I update items via CSV? Getting error: Vendor/Subsidiary must be unique

edited Jun 2, 2025 2:39PM in Ask A Guru 2 comments

I've successfully uploaded my serialized item records via csv, but if I try to update them in any way I get the error back 'Vendor/Subsidiary must be unique'.

Are other people aware of this issue and how do I avoid this?

Do I just need to not map any of the fields relating to Vendor and/or Subsidiary?
