Can someone point me in the right direction for how to create a contact with a vendor relationship in suitescript? The contact piece I understand, but I am struggling to find info on how the relationship works edit: looking to create a contact role with an associated vendor.

You create the contact and set the company to the vendor ID

Ah yes, what about setting roles? I misspoke on my original post. Looking to create an associated role with a vendor.

record.attach is your primary choice whenever you use the attach button

Brilliant thanks @battk
