Web Repository (SAP
transaction SMW0) is the older technique; it is used by many customers.
The Mime Repositor
(SAP transaction SE80) interface is a little bit more complicated but offers
more functions, e.g. a folder structure.
Repository needs 3 RFC calls to read a script instead of 1 for Web Repository,
but if you activate the GuiXT cache and use the "VersionNumber"
statement this does not make a big difference.
