For batch & of material & &, no class could be determined

What causes this issue?

The system has been configured so that batches have to be classified for
the current movement type. Since neither the material nor any batch of
this material has been classified, batch &V1& cannot be classified for
the current movement type.

System Response

Depending on how the system is configured, either a warning or an error
message is issued.
If the message issued is a warning (<LS>W</>), the system allows you to
enter batch &V1& without classification. The warning is, however,
issued to prevent you from making a wrong entry.
If the message issued is an error message (<LS>E</>), you cannot post
batch &V1&.

How to fix this error?

You either have to classify material &V2& in the material master or
manually create batch &V1& in the batch master and classify the batch
there.
As soon as a class has been assigned to the material or a batch of this
material, you can classify other batches of this material upon goods
movements.
