&2 cannot be transported along with "&1"

What causes this issue?

At "&V1&" you selected the indicator "&V2&: &V4&". However, you did not
choose object group "&V1&" for the transport. This is why &V2& cannot
be transported.

System Response

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

How to fix this error?

If you want to transport &V1& including the assigned &V2&, choose
object group "&V1&" for transporting, and make further selections if
desired. Alternatively, on the selection screen you can also find a
different object group, in which &V2& can also be chosen.
