The Data Integration Service uses the default sequence flow in different ways for the different gateway types. On an Exclusive gateway, the Data Integration Service runs the object on the default sequence flow if the conditions on every other sequence flow evaluate to false. On an Inclusive gateway, the Data Integration Service runs the object on the default sequence flow regardless of the conditions on every other sequence flow.

You do not need define a condition on the default sequence flow. The Data Integration Service ignores any condition on the default sequence flow at run time. When a sequence flow includes a condition and you select the sequence flow as the default, the Developer tool displays the condition as read-only.
