Enter a positive numeric value.
A required feed quantity is empty, zero or unreadable.
Why does this happen?
The amount must be greater than zero: daily feed per animal in the ration editor, or the total feed used for the group when applying a daily ration.
How do I check it?
In the ration editor, enter the daily amount for one animal in Fed kg per animal. Use the feed’s weight as offered, including moisture.
When applying a daily ration, enter the total weight actually fed to the selected group in each feed’s actual kg field.
Retype the amount using your app language’s decimal mark, then tap Save once. Read any quantity confirmation before continuing.
How do I verify the result?
Check the saved ration amounts or today’s feeding record and stock movements.
How do I keep my records safe?
Check the existing record before repeating a save so each feeding is recorded once.
