The design-tools/data-integration/samples/transformations directory contains the following example KTRs that show how to use this step:
Example KTR File | Description |
Row Normaliser - Simple example.ktr | Shows a simple example of normalizing sales data. |
Row Normaliser - turn a single row into 3 rows.ktr | Shows an example of splitting fields into columns then normalizing the columns. |
Metadata injection support
