Evaluating Invoices for Event-Based Revenue Management

The Revenue Management Engine controls the process of automatically analyzing  collectibility and then making revenue recognition decisions for your manually entered and imported invoices. This process is automatically enabled if (1) • You have defined a revenue policy, or (2) • Invoice lines are associated with contingencies.  The Revenue Management Engine decides whether to initially distribute revenue to an earned or unearned revenue account.  Once this decision is made, AutoAccounting creates the actual accounting distributions,   either by AutoInvoice (for invoices without rules) or by the Revenue Recognition program (for invoices with rules).

When I selected an invoice from Transaction Workbench, how would I know if a particular invoice has no rules or without rules. I would appreciate if can direct me to a particular tab and/or fields. Thanks much.
