Easy enhancement workbench modification

Hi all,

I'm trying to modify an extension on my web iu related to business partner, it is a new block. When I see the function module which is generated (a Z module) it says that the file is generated by the easy enhancement workbench but when I try to find it with EEWB transaction there are no projects in my system.

There are other transaction or customizing point to change an eew?

Thanks.

Regards.
