Creating an Otherwise rule tells the DPA where to send a work item if the conditions of other rules are not met.
Open the Rule Properties dialog as described in Configuring Simple Rules for DPAs.
In the Rule Properties dialog, select the Otherwise option.
Note: You can create only one otherwise rule for each DPA.
Click an activity in the Available box and click to move the activity to the Selected box. The DPA is now configured to send the work item to this activity.
To save the rule, click the OK button.
