Introduction

Mapplet.
A Mapplet is a reusable object that represents a set of transformations. It allows you to reuse
transformation logic and can contain as many transformations as you need. A Mapplet can contain
transformations, Reusable transformations and shortcuts to transformations.

There are two types of mapplet.

 Input Mapplet (For the input port).
 Output Mapplet(For the output port).

Description
In this example, we remove duplicate row using mapplet. There are following steps to remove
duplicate row using mapplet
.
• Create Repository and Folder in Informatica Repository Manager.
• Import Source database and create/import target table in Informatica Designer.
• Create mapplet, First create input mapplet (creating port for input the column), then create
aggregator transformation (add dummy port for column and check group by box to this
column and then count data using count function). Then create filter transformation and filter
the unique and duplicate data using expression. Then passes all column into output mapplet
transformation.
• Then Create Mapping using mapplet.
• Create workflow and execute workflow.
• Check log file.
• Then Review output data.
