Custom Generation

Custom Generation

Create custom generation rules to generate data for string, numeric, and date data types.
Custom generation rule is a global rule. To create custom generation rule, import a PowerCenter mapplet. Mark at least one input and one output column as required.
The following image shows the custom generation parameters:
The New Generation Rule dialog box shows the input and output columns of a PowerCenter mapplet that you import. The image shows one input column and one output column marked as required.

Custom Generation Example

An EMPLOYEES table contains columns for first name and last name. Create and assign standard generation rules to generate first names and last names. Create a custom generation rule to combine the first and last name of an employee to generate the full name in the target table.
