Python Transformation

Effective in version 10.4.0, the Python code component in the Python transformation is divided into the following tabs:

Pre-Input. Defines code that can be interpreted once and shared between all rows of data.

On Input. Defines how a Python transformation behaves when it receives an input row while processing a partition.

At End. Defines how a Python transformation behaves after it processes all input data in a partition.

In upgraded mappings, the code that you entered in the Python code component appears on the

On Input

tab.

Review the code to verify that the code operates as expected. If necessary, refactor the code using the

Pre-Input

On Input

, and

At End

tabs.

For information about how to configure code on each tab, see the "Python Transformation" chapter in the

Informatica Data Engineering Integration 10.4.0 User Guide
