You can add ad hoc measurements or measurements that were not specified on the originating task definition, to a task online or offline. Any measurements already displayed on the Task Measurements page that you can navigate to from Task Details, are those that were added to the task beforehand.
You can add measurements by clicking Measurements from Task Details and then clicking Add Measurement. You must select the step for which the measurement is applicable and then select the measurement parameter to be added to the task in order to add it.
You can record measurement values when you partially complete or complete work and then sign off these values.
You can also remove measurements on the Task Measurements page provided that the measurement was not originally defined on the synced task and has not yet been signed off.
