When I try to create a vendor I get an error upon save saying that I have invalid Accounts Payable and Receivable.   I don't have a need for these accounts as my PO requests will not be going directly to a vendor, I also don't see any tabs or fields in the vendor creation for such accounts.   I went ahead and created a receivable and payable account under "chart of accounts" in the "implementation guide"  under "settings."   This didn't fix the problem, nor do I see a place to add them under the vendor creation card.
