I did the same steps mentioned in the following link
Local client copy (step by step process)
and I went to check it from SCC3. It told me that it successfully completed. but when I go to check the usernames which should be copied by the local copy, I find nothing, and the only user I have after finishing the local copy is SAP* only which I can't use it to create an administrator because there is no template roles or any thing on the new client.
FYI I selected SAP_USER and another time SAP_PROF. the result is the same. in addition I can't make the local copy by selecting SAP_ALL or SAP_CUST and pop up me with an instruction screen.
