Enter a valid numeric value.
A number field contains an unreadable or negative value.
Why does this happen?
Optional number fields only accept zero, a positive number, or a blank value, while required quantities must be greater than zero.
How do I check it?
Check the field label: Stock quantity kg is incoming feed weight, price per kilogram is the unit price, and total cost covers the whole delivery.
Retype the number using your app language’s decimal mark. Keep units and currency signs outside the number field; leave optional fields empty until you have the figures.
Review the remaining numbers, then tap Save once or continue with the recommendation. Read any quantity confirmation before continuing.
How do I verify the result?
Compare the saved amounts with your delivery note, or review the recommendation and its inputs.
How do I keep my records safe?
Check purchase records before entering the same delivery again.
