Mapplet
In the previous section, we saw how to make a transformation reusable. Going further, you
might also like to reuse logic that was implemented using multiple transformations. The
group of transformations that can be reused is called as mapplets.
Mapplets can be created in the Mapplet Designer in Informatica PowerCenter Designer.
Mapplets allow you to reuse groups of transformations in multiple mappings. As is the case
with reusable transformations, in order to use mapplets, the metadata requirements of the
mappings should be exactly the same.
You can use the Mapplet Designer to create mapplets with new transformations or use ex-
isting transformations.
To create a new mapplet, perform the following steps:
1. In the designer, navigate to
Tools
|
Mapplet Designer
, as shown in the following
screenshot. Then, click on
Create
.
2. Specify the name of new mapplet as
MPLT_REUSABLE
.
3. Add the transformations in the mapplet as per your logic. We are using filter and
expression transformation to create sample logic.
