You can connect literals to the following elements if they do not have incoming relations:
- output parameters
- return parameters
- operation input pins
Select one of these elements to which you want to connect the literal, then drag out the literal icon from the elements toolbar. In the example on the left, the pin key of the call operation retrieve was selected. You can place the literal anywhere within the diagram pane at the desired position. As soon as you release the literal, the relation to the selected element is drawn.
