Informatica provided us the capability to combine the multiple transform in a single one (in form of Mapplet ) and use them in Multiple Mapping

What is Informatica mapplet :

Informatica Mapplet is the reusable object which is created with set of transformation (combined by some Logic), so that can it can be reuse in multiple mappings directly.It is created in Mapplet Designer in Informatica designer

Component of Mapplet:

Mapplet input:

We can give data to mapplet from source definetion or any other transformation via Input port of Mapplet.

Mapplet output:

Mapplet provides the ouput port , from which we can pass data from mapplet to the remaining part of Informatica Mapping

Steps to Create Mapplet

  1. Go to Tools->mappletdesigner->create->give a name

  2. From transformation menu->create->mapplet input

  3. In mapplet input transformation create required input ports

  4. Create required group of transformation like sorter,expression

  5. Drag the ports from mapplet input to the transformation

  6. Create mapplet output transformation

  7. finally save the mapplet in the repository

Some Properties of Mapplet:

Changing in Mapplet ,will affect all its related mapping where it is used, so its necessary to design it correctly before using it

Mapplets don’t have source/ target Definition .Data is transferred via input/output port only

I have been trying this since a week now. But I would like to use Filter Transformation or any alternative way to Filter records in Informatica Developer (Informatica Data Quality).

I have a field called Output which is generated in a Mapplet which contains two cases, 'pass' or 'fail'

I would like to view the results of only fail records.

Is there a way I can do this using a Mapplet?

Thank you.
