When creating a new workflow request, a Policy (synergy document) may be linked. This is done by selecting the Synergy Document field on the General Tab of the Definition of the Request. The Policy document will be displayed as a Icon on the Top Upper Right Hand Portion of the Request screen. The example is from Version 255 of Synergy Enterprise.
This policy document (and I have attached an example for you to view) can be used to show Resources the flow of the Request during each step of the process. Additionally, it may be used to document information on each of the fields used within the Request.
