If a time task exists for a given activity (service order and person time tasks), it can be chosen as ‘task’ for time efforts created in the mobile app. This can generate an excessive number of tasks. For 5 operations, at least 10 (depending on /PACG/ECM_SOLAF - Subtasks - Filter config it can be more) tasks are sent – 5 referring to the person, 5 referring to the service order. This approach is recommended when time tasks are not person but service order dependent.
