Modify values from a single row

You can use the Modify values from a single row step to build complex hierarchical data in two ways:

• You can take hierarchical data from a previous step and modify the data using data from incoming incoming fields using a series of path definitions for the single row of input. .

• You can also take non-hierarchical data and create a new or modify an existing hierarchical data structure and pass the structured data to other steps.
