Definition &1 is in SAP name range! Create anyway?

What causes this issue?

The name &V1& is reserved for SAP AG for action manager definitions.
The definition &V1& should therefore not be created in a customer
system.
However, if you create the definition it is possible that it will be
overwritten or deleted in a subsequent release.

want to create.
