mapplet is a set of transformations that can be reusable. where as resuable transformation is a single transformation that can be reusable.
if you create mapping variables or mapping parameters in mapplet that can not be used in another mapplet or mappings. The variables that are created in a reusable transformation can be usefull in any other maping or maplet.
the transformation logic is hidded in mapplet where as it is transparent in resuable transformations.
source definitions can not be included in the resuable transformatins, we can add sources in the mapplets.
the followiing transformations are not included in the mapplets:
Joiner transformations
Normalizer transformations
Non reusable sequence generator transformations.
Pre or post session stored procedures
Target defintions
Power mart 3.5 style Look Up functions
XML source definitions
IBM MQ source defintions.
but these are used in resuable transformations.
