Internal Order Type Error

Dear Experts,

I have created a new order type in the system. it is showing under the transport request but not at the list of available order type while creating the internal order master through KO01. Also its not showing KOT2_OPA, but if i try to recreate the same system gives me an error message order type already exist. Further at number range level it is showing the new order group.

Please suggest how to overcome the issue.

Regards,

Ribhu
