ORA-13112: cannot delete topo_geometry layer [string] from topology

What triggered the Error:

It was not possible to delete the specified topo_geometry layer from the topology.

What should we do to fix it:

Check USER_SDO_TOPO_METADATA to see if the specified topo_geometry layer is part of the topology. Only those topo_geometry layers which are part of the topology can be deleted from it.
