Adding Transformation and Lookup Details

You can add transformation and lookup details to a mapping specification in the Mapping Specification grid.

Adding transformation details involves setting up:

• Business rule
• Extended business rule transformation

Ensure that you define business rules under the Transformations node for the same ETL Option as the Project ETL. For more information on defining business rules, refer to the Defining Transformations section.

Adding lookup details involves setting up:

• Trans lookup condition
• Lookup reference column
• Lookup on

Ensure that you scan the required table in the Metadata Manager to set trans lookup condition.

Adding Transformation Details

To add business rules to mapping specifications, follow these steps:

1. Go to Application Menu > Data Catalog > Mapping Manager.

You can add business rules for multiple source columns.

8. Click .

To add extended business rule transformations, follow these steps:

1. Right-click the header menu of the Mapping Specification grid.



2. Select the Extended Business Rule Transformation check box.

The Extended Business Rule Transformation column is now available in the Mapping Specification grid.

3. Click .

You can now edit the Mapping Specification grid.
