PO on Vendor A and material recd by vendor B

Hi

The PO is raised on vendor A to supply the material.

However the delivery address is of another vendor B.

The issue is how will the GR be handled in SAP only after confirmation from vendor B of receipt.

Also it is possible that the vendor B may be in a different country.

Here the issue is to handle the customs payments.

Is there a standard process to implement the above?

Thanks in advance.
