Enhancement spot &1 cannot be renamed because enh.impl. exists

What causes this issue?

For enhancement spot &V1&, at least one enhancement implementation
exists. Therefore, renaming the enhancement spot is not possible.

System Response

The action 'renaming' is terminated.

How to fix this error?

If the enhancement spot needs to be renamed all the same, first all
existing enhancement implementations that are assigned to this
enhancement spot must be deleted.
It is not enough to simply delete all the BAdI implementations of an
enhancement implementation; the enhancement implementations themselves
must also be deleted.
The implementing classes do not have to be deleted.
