Adding/Deleting/Moving Transforms

At the very heart of any integration are the transforms. Each transform defines a set of actions either to data or as a result of the data. The order of the transforms defines their Transform Execution & Data Flow.

Adding a Transform

Transforms can be added by dragging them from the palette to the surface.

The transform can either be joined to another transform using the connector (or arrow) or the Transform Setup Interface for the transform can be opened by double clicking it.

Opening the Transform Setup Screen

The setup screen will open under the following conditions:

  1. If the transform is either a reader or a task transform.
  2. If not a read or task, the setup screen will open only when the transform is connected to a configured parent transform.
If the preceding conditions are not met, double clicking will not perform any action.

Connecting Transforms

Transforms are connected through the connector object, located on the Transforms tab.

The connector is an arrow, where the head, indicates the data flow direction.

The transaction types and fields are immediately propagated from the parent as soon as the transform is connected. This breaks with v4.1 and earlier releases where the transform needed to be opened for the transaction types and fields are immediately propagated.

Connection Rules

When connecting transforms, the following rules are applied:

  1. Each transform can have at most 1 transform as input.
  2. Reader transforms can only have tasks as input transforms.
  3. Transforms cannot be connected in such a way that a cycle is created.
  4. Each transform may have zero or more outputs (as shown below). When a transform has multiple outputs or child transforms the order of execution is determined by the child transform's Priority
  5. If Modifying Existing Transform Logic the transaction types and fields must match.

Using the Connector Object

  1. Drag the connector from the palette onto the Design Surface.
  2. Select the connector and drag one of the endpoints to a transform until the transaction is highlighted and the endpoint changes to white.
  3. Repeat this process for the other endpoint. If the connection cannot be made (as one of the rules is broken) you will receive an error message.

Selecting & Moving Transforms

Individual transforms can be selected by clicking the icon.

Multiple transforms can be selected by dragging an area with the mouse.

Transforms can be moved either individually or as a group.

Deleting Transforms

Transforms can be deleted by selecting transform with the mouse and pressing the Delete button on your keyboard.

Multiple transforms can be deleted by selected an area with the mouse and again pressing Delete.

A prompt will be displayed asking to confirm the action.
