I have few questions around creating a PO.
1.The system allows us to create a PO for contact person and different invoicing party which are not associated with the main vendor for which a PO is created. why is the system allows us to create for other partners functions which are not created for main vendor used in PO?
2.The system even allows us to posts the invoice for a different invoicing party. why?
3.what are the system implications and affects on different accounting docs which get generated?
Thanks in advance.
