You can add conditional logic to a process flow so that different activities run based on the return code of a preceding activity. For example, you could execute one activity if a job returns a return code of 1 and another activity if a job returns a return code of 0. In this way you can build conditional branching into your process flow.

Open the process flow in Spectrum Enterprise Designer.
Double-click the transition between two activities of the flow.

A transition is the line that connects two activities. For example, the line between the GeocodeAddress activity and the Run Program activity shown here is a transition:

The Transition Options window appears.
Select the type of transition you wish to add.

Simple

Select this option if you always want this path in the process flow to run.

Conditional

Select this option if you only want this path in the process flow to run if the upstream activity returns a specific return code or return codes, or a range of return codes.

Otherwise

Select this option if you want this path in the process flow to run only if the conditions in the other transitions leading from the activity are not met.
Note: Only one Otherwise transition can exist among the transitions leading from an activity.
Click OK.
To configure which transitions trigger an activity, right-click the activity, select Input modes, then choose one of the following:

First Input

The first transition coming into this activity, whether through a Simple, Conditional, or Otherwise transition, triggers the execution of the activity. Other transitions are ignored.

All Inputs

The activity does not run unless all transitions coming into this activity are taken.
To configure which transitions leading out of an activity are taken, right-click the activity, select Output modes, then choose one of these options:

First Output

The first transition that evaluates to true is taken. Other transitions are ignored, even if their conditions evaluate to true.

All Outputs

All transitions that evaluate to true are taken.
