Additional context
Please investigate and address this issue promptly to ensure the Enatega SingleVendor Admin system maintains a high level of reliability and accuracy in data processing.

Thank you for your attention to this matter.

Start at the SingleVendor Admin product-management area and trace validation for the discount, stock, and price fields. No file or test is named; done means negative inputs are rejected in each named field and regression coverage verifies the behavior.
