Commodity
Once an inspection is created, the produce (or commodity) cannot be edited. This restriction exists because each produce has its own defined set of processes, which determines the specific data that needs to be collected during the inspection. Changing the commodity would require a completely different data structure, which is why it remains locked once the inspection begins.
Variety
Unlike commodities, the variety can be modified provided the inspection is not approved. The modification can only be done on the Clarifruit Web App, not the mobile app. For more information on how to change the variety: Can I change the produce variety of an inspection?
