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

CAUSE&
You entered a goods invoice with delivery costs.
In an item for delivery costs in 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 or delivery costs item for invoicing party &V3&. Another item
refers to purchase order &V2&. The system copies the invoicing party
from the first item to all items, in this case V3&.
