Top level package could not be deleted because of remaining objects

What causes this issue?

When deactivating BW Search completely, the framework also removes all
generated SAP HANA views and packages. The top level package is also
removed as defined in transaction RSOSM. It might not be possible to
remove the top level package because objects exist in subpackages which
have not been deleted. This can happen because objects exist in these
subpackages which have not been generated by BW Search, and the search
framework therefore does not know about these objects.

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?

This error is not critical. If you want to remove all generated objects
completely, you have to clean up the top level package &V1& manually.
