This workflow creates a manual activity for a user to review service invoice details that do not correspond with the service authorization associated with the invoice. During invoice processing, certain details on a service invoice line item (SILI) must correspond to the details on the service authorization that is associated with the invoice otherwise the invoice will not be paid. The default implementation of this operation allocates the activity to the invoice exception processing work queue for a financial user to review. Agencies may wish to alter this default behavior, for example, by routing the activity to a different work queue. The reviewer can choose to make changes to the service invoice line item and submit for reevaluation or deny/cancel the SILI. Once this activity is completed, the workflow is also completed. This manual activity is allocated using a function allocation strategy. The modeled operation for this is: curam.cpm.workflowprocesses.impl.WorkflowAllocationFunction.siliExceptionProcessingAllocationStrategy.
