What are the consequences of selecting "close without transport" option for a standard change list

Hi All,

Few active and few in process objects of a configuration scenario have accidently moved into a list whose status is transportable (not open).

I'm unable to access those objects.If I select close wothout transport, would I be able to further modify/acess these objects or not?

Please suggest!

Thanks,

Indu Khurana.
