Material subject to serial number not possible for external warehouse

What causes this issue?

The function you want is not supported in transaction <ZH>IW8W</>, as
the serial numbers for the current time point are not automatically
transferred to the inbound delivery.

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

System Response

How to fix this error?

Instead use the transaction for updating goods receipts for the
refurbishment order (for example, <ZH>MB31</>).
Note that even when using transaction <ZH>MB31</> you must subsequently
maintain the serial numbers manually.
