Nathan, thank you for your quick response.
If you don't mind, tell me URL of the site you found or your search condition when you tried.
Unfortunately, I couldn't find any sites which explain uploading whole setting of IMG(SPRO) when I tried.
There are some sites to show how to upload a certain setting such as a part of HR, market data of FSCM, and so on. But those are not what I'd like to know.
I need information about a scheme to upload all IMG(SPRO) settings through a file format.
I guess SAP has the special transaction, service, or scenario of LSMW (or any other migration methods) for it.
Thanks,
Yugo
