In a past newsletter I saw a vendor announcement for a tool that allowed the logical copying/extraction of SAP selected subsets of data from one client (say, production) to be then copied into another. I have searched your site for the name of the tool/vendor to no avail. Can you help?
I believe the site you are looking for is http://www.getgamma.com/index.cfm Their product is called InfoShuttle and it does exactly what you described. I will re-add their link to my site again (www.giovannidavila.com/sapbasis).
