The Consumables Tracking Report, like any other analytics, requires the presence of data in the system that can be included in the report. In order for data on consumables to appear in the report, your employees must record the consumption of specific materials when performing tasks. The detailed description of how the consumables tracking function works can be found here: Consumables Tracking.
