There are a few possible scenarios to check:
1. Verify the invoice value and then try applying the discount.
2. Check the product prices and the discount applied.
For example, if the product price is ₹60 and you’re trying to apply a discount of ₹155, it will cause an error.
3. Check the discount type.
In the above example, if the discount is applied on the unit price as ₹155, the system will show an error saying, “Discount cannot be greater than the total amount.”
Note:
In such cases, please suggest the customer to change the discount type to “Net Amount.”
