Manage work: work management: W052 daily returns review - SA/PAYE auto-coding exceptions

With the introduction of auto-coding, work items populated the list where auto coding was unable to take place and manual action was required. From October 2014, some automated checks were introduced so fewer work items are created which require manual action.


A work item is created when manual action is required, for example cases where the auto-coding inhibition (ACI) signal is set, or where the case is excluded from auto-coding.
