InfoObject & ( & ) is not active

What causes this issue?

InfoObject &V1& ( &V2& ) is not actively available. It is only
available in version &V4&.
A structure can only be activated with active InfoObjects. Therefore,
all InfoObjects that go into the structure must be actively saved.
However, this is no the case with InfoObject &V1&.

System Response

Function was terminated without a change to the database.

How to fix this error?

Activate the InfoObject &V1& (&V2&) in the InfoObject maintenance.
Afterwards, you can repeat your activation.
