Answer Posted / sri
A shortcut is a reference (link) to an object in a shared
folder, these are
commonly used for sources and targets that are to be shared
between
different environments / or projects. A shortcut is created
by assigning
'Shared' status to a folder within the Repository Manager
and then dragging
objects from this folder into another open folder; this
provides a single
point of control / reference for the object - multiple
projects don't all
have import sources and targets into their local folders.
A reusable transformaion is usually something that is kept
local to a
folder, examples would be the use of a reusable sequence
generator for
allocating warehouse Customer Id's which would be useful if
you were loading
customer details from multiple source systems and
allocating unique ids to
each new source-key. Many mappings could use the same
sequence and the
sessions would all draw from the same continuous pool of
sequence numbers
generated.
