Problem to getting Smartform Name from NACE

Hi all,

I have got one "Z" T. code related to EXCISE INVOICE. I want to know the Smartform name for the same. I got the T. COde from the Program, but when I try to open it in the smartforms, it shows "This smartform does not exist".

How can I get the smartform name from NACE, pls clarify step by step (IN NACE)

Thanks
