Mapping is a set of transformations used to Map source tables to target data tables.
Mapplet is nothing but a reusable Mapping.. In Mapplet you won't specify the actual targets..
There is one more difference, if a variable and paramater is defined in a mapping cannot be used in a mapplet.
The following should not include in a mapplet.
- Normalizer transformations
- Cobol sources
- XML Source Qualifier transformations
- XML sources
- Target definitions
- Pre- and post- session stored procedures
- Other mapplets
The exact reason i why these should not used i dont know.
