Error message on ERP Vendor UI

Hello Expert,

I am using out of the box "ERP VENDOR UI".

I am getting below error message on "ERP Vendor UI".  Can you please tell me how I can fix this error?

Error Message: "Role Vendor requires purchasing Organization data".

Also, when I click New button on "Purchasing Organization" section I don't see field to add "Purchasing Orgnization" .

Thanks,

Meghna
