Once a precondition rule is created, it can be assigned to any existing audit rule. When a rule is linked to a precondition, the rule will only be evaluated if the precondition is determined a success after it has been assessed. If the precondition is assessed and it fails, the rule that it is linked to will be not be evaluated.
On the Expense Audit Settings screen, in the Expense Audit Rules section, click on the pencil icon of the rule that is to have a precondition rule linked to it.
The Has Precondition Rules checkbox is an indicator field. If no precondition rules are linked to the rule, this checkbox remains unticked. Click
to add a precondition rule. This button is also used when adding or deleting any precondition rules after the first one is selected.
The Precondition Rules window will appear listing all the active precondition rules that are available. Select the precondition rule by checking on the Include checkbox. Click
followed by
to return to the Expense Audit Settings screen.
The Expense Audit Settings screen will be refreshed and the Has Precondition Rules checkbox will be updated with a tick. Press [Save]. Once the link is saved, the audit engine will validate the precondition rule first before it assessing the rule that the precondition rule is linked to.
