Table Maintenance

Hi All,

Can you please help me out in this situation :

I have assigned a issue to moving maintenance on table T023 out of SPRO and directly into the transaction OMSF which I believe basically make the table no longer cross-client. Now I want to know if is it true that to move from SPRO to a transaction it had to be done before going live. I think this is not possible once we go live, can you please tell me if I am right and if I am not then can you guide me how can we achieve this (how can we movemaintenance on table T023 out of SPRO and directly into the transaction OMSF or any ztransaction ).

Thanks,
