Overview
Transformation flows are created by combining various steps through connectors. Use the information below to learn more about these steps and connectors.
Steps
These are the three types of steps that can be included in a transformation flow.

Connectors
Connectors are used to join steps together and create a relationship between them. Data will flow from one step to another step. Click on a step to reveal its connecting points. These points are then used to connect one step to another. The flow of a connector is represented with an arrowhead at the end of it.
Connection rules
These rules are applicable on step connecors (running left to right).
- An input step can be connected to only one transformation or output step.
- A transformation step cannot be connected to an input step, but to another transformation or output step.
- All types of transformation steps, except the split step, can only be connected to one other step.
- A split step can be connected multiple times.
- Connections can only be made to an output step, but it cannot be the origin of a connection.
Connector Functions
Once a connection is created between steps, right-click on it to see the functions that can be performed.
These are explained below:
Function | Description |
---|---|
Edit Flow | To configure the mapping between the data fields in the connecting steps. |
Break Connections | To delete the selected connection. |
Breaking a Connection
Once a connection is created between two steps, it can be broken or deleted. Simply right-click on the connector itself and select Break Connections.
Alternatively, right-click on one of the steps, and click on Break Connections. This will break all the connections associated with that step.
Confirmation will be required before the connection is deleted. Just click on the Confirm button to do so when the popup appears.
