  • Error Code: CN809

    Error Message: Enter a time unit, since you have entered either work or actual work


    Summary

    This error occurs when you enter values for work or actual work in a time-related entry but fail to specify the corresponding time unit (such as hours or days). The system requires a time unit to correctly interpret the quantity of work entered.


    Root Causes

    • User enters work or actual work quantities without specifying the time unit (e.g., hours, days).
    • Missing or incorrect configuration of time units in the work scheduling or time management settings.
    • Master data for the activity or operation lacks a default time unit or it is not maintained properly.
    • Data entry screens or interfaces do not enforce mandatory time unit input, leading to incomplete entries.
