Customizing Request not Prompting

Hi Everybody

I configured some settings in spro like PROUCT ALLOCATION, ATP Group etc.

While creating those objects customizing request was assigned to all my configuration settings in spro.

Recently i unlocked the request in se03 and deleted the Customizing requests.

Now when i go to the same transaction and save the object it is not prompting me customizing request.

I would like to assign custoizing request for all my objects which were created earliar.

Please help.

Thanks in Advance.
