Working with Transformations Built On the Custom Transformation
Working with Transformations Built On the Custom Transformation
You can build transformations using the Custom transformation. Some of the PowerCenter transformations are built using the Custom transformation. The following transformations that ship with Informatica products are native transformations and are
not built
using the Custom transformation:
Aggregator transformation
Expression transformation
External Procedure transformation
Filter transformation
Joiner transformation
Lookup transformation
Normalizer transformation
Rank transformation
Router transformation
Sequence Generator transformation
Sorter transformation
Source Qualifier transformation
Stored Procedure transformation
Transaction Control transformation
Update Strategy transformation
All other transformations are built using the Custom transformation. Rules that apply to Custom transformations, such as blocking rules, also apply to transformations built using Custom transformations. For example, when you connect a Custom transformation in a mapping, you must verify that the data can flow from all sources in a target load order group to the targets without the Integration Service blocking all sources. Similarly, you must also verify this for transformations built using a Custom transformation.
