Adding connections
Use the Graphical Data Mapping editor to create connections between the input and output objects in your mapping.
Before you start:
- Read the following concept topics:
- Create a graphical data map using the Graphical Data Mapping editor. For information about how to do this, see Creating graphical data maps.
- Add input and output objects to your graphical data map, as described in Adding input and output objects.
You can create a connection in a graphical data map by using one of the
following methods:
- Move the cursor anywhere over the required element in the input object, then click and drag the connection over the required output element and drop. You can also create the connection from the opposite direction, by dragging the connection from the output element to the input element. You can also use the grab handle that appears when you hover over an element to click and drag the connection.
- Select the appropriate input or output object and right-click to display the context menu, then select Quick Link. An outline view of the opposite data structure is displayed; if the Quick Link action is invoked on an input object, a quick outline view of the output data structure is shown, and if the action is invoked on an output object, a quick outline view of the input data structure is shown. You can then use the quick outline view and its built-in filter to find and select the required element. When you have selected the required element, a transform is created in the editor.
- Select the required input element and right-click to display the context menu, then select Create connection. This method allows you to carry out other actions in the editor that require the use of mouse clicks (such as expanding output elements, or using the scroll bars) while a transform is being created.
Some transformations, such as the Assign transform, require a connection to an output object and but not to an input object. You can create these transformations either by invoking the Create Connection action, or by clicking anywhere on the output object or its grab handle and dragging onto the empty space.
The following steps show how to add connections using the drag and drop method:
- Move your cursor to the element of the input object that
you want to map:
- Click anywhere in the input element, or on its grab handle
, and drag to the output element. A connection is created between the two elements, and a transform is assigned, based on the number and type of input elements.
- To add another input element, create a connection between
the input element and the transform:When you add an additional input connection, you are prompted to specify either a primary connection or a secondary connection (Supplement). If you specify a primary connection, the default transform changes to one that allows multiple primary inputs, such as Local Map, Concat, or Join. For example:Specify a secondary connection if you want to make additional input data available to the transform.

When you have created the connection between your input and output objects, select the required transform as described in Specifying a transform.
