Enter comments for Input and Output transformations.
In a mapping, you can view comments associated with an Input or Output transformation by holding the pointer over the transformation name in the mapplet. You can clarify the use of a mapplet and its ports by creating descriptive comments or instructions in the Description field of Input and Output transformations. You can even include links to business documentation.
Create an Output transformation for each output group you need.
You can pass data from each mapplet output group to a different mapping pipeline. Create an Output transformation for each output group you need.
To create mapplets from existing mappings, copy the objects from the mapping into the Mapplet Designer.
Configure Sequence Generator caches appropriately.
You can include a reusable Sequence Generator transformation in a mapplet. If you use the mapplet in several mappings and each mapping expends a large number of values in a session, you might want to configure the cache size for reusable Sequence Generator to limit the number of unused values.
To keep existing mappings valid when you edit a mapplet used in a mapping:
Do not delete connected ports in an Input or Output transformation.
Do not change the datatype, precision, or scale of connected ports in an Input or Output transformation.
Do not change a passive mapplet to an active mapplet or an active mapplet to a passive mapplet.
