Different invoicing party & planned for del. costs item in PO &

What causes this issue?

You entered an invoice for delivery costs.
In a delivery costs item for purchase order &V2&, the invoicing party
is &V1&. You are now posting the invoice to &V3&. This can be for one
of two reasons:
You entered &V2& in the field <LS>Purchase order</>, and &V3& in the
field <LS>Invoicing party</>.
You entered a multiple allocation. The first item refers to a purchase
order with invoicing party &V3&. Another item refers to purchase order
&V2&. The system copies the invoicing party from the first delivery
costs item to all items, in this case &V3&.
