A Transform unit is used to modify the output of a data source by creating a new parameter structure and mapping existing attributes to the new parameters. It is often used to prepare output for a Merge unit.
To use a Transform unit, you first create a new property, which can be an object, an array or a literal, that matches the structure of the data source. You then add attributes to the structure and then modify the value of each attribute using references, Axel-f functions and operators.
To add a Transform unit, follow these steps.
In the Pipeline dashboard, select Transform unit from the Library to add it to the pipeline.
Drag a line from a unit to the new Transform unit.
Click the Transform unit open the Mapping Editor.
Click New Property and give it a name. Choose either Object, Array or Literal, then click Create.
Expand the new property by clicking the Down arrow.
Drage selected attributes to highlighted New Property areas in the structure.
Modify the values of the parameters as required.
Click Done to save your changes.
