Once a roster line item has been submitted for processing, as with a service invoice line item it must be validated to make sure that the service delivery has been authorized by the organization. This includes:
If the roster line item fails the matching or validation process, a task is created in the roster exception processing work queue stating the reason why the roster line item could not be processed. The user can correct and resubmit the line item for processing, or deny the line item from the exception processing task. The roster line item can also be corrected and resubmitted directly from the user's workspace. Once resubmitted, the roster line item goes through the process of matching and validation again, and if successful, the task is closed.
The validation of a roster line item is limited to ensuring that the expected amount of service is accounted for, and that the authorized amount of service is not exceeded. No additional validation, for example checking whether a certain amount of allowed absence has been exceeded, is performed by CPM OOTB, though it is possible to extend CPM to do so - see the CPM Developer's Guide for more details.
