Inbound delivery item for SC component was generated from PO &1 &2

What causes this issue?

The inbound delivery item refers to a purchase order of a subcontracting
component for a subcontractor. These goods should be posted directly
into subcontracting stock. Order item &V1& &V2& has the indicator
SC-vend for the delivery address.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

System Response

The goods are not relevant for putaway and could not be distributed to
the decentralized Warehouse Management system.
The system splits subcontracting components from other goods and, where
necessary, creates a separate inbound delivery for the subcontracting
components. In this case, you receive a status message in the dialog for
transaction VL31N informing you that several inbound deliveries have
been created. The system displays the inbound delivery numbers when you
save.
