Answer / 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.

Answer / krithi

Shortcuts allow you to share multiple objects within the
repository i.e., we can use an object in the shared folder
without creating or copying. If the original object
changes, the shortcuts reflects the changes.

Whereas a Reusable Transformation can be used only within
the mappings in that folder.

The shortcuts include:

Source, Target, Tranformation, Mapping, Mapplet,Reusable
Transformation, Business Components.

I still need further explanation about the difference between active and passive transformation with some examples.Thank You
