After creating a Business Process , you can check to see if there are any problems such as activities that are not connected or an incorrect number of output links from an activity.
On the toolbar, click Validate BP Model.
If an error is encountered, a message box displays information about the error. If there are no errors, a message appears stating that there were no errors.
If an error message displays, see Saving an Unfinished Business Process for information on repairing errors. Repairing the error may entail such items as adding logic to Decisions or adding attributes to activities.
