Because of an overpayment, you have now a difference in your Payment Allocation and a positive amount in Open Amount. If you select Action > Apply discount or credit and add a negative amount, you receive the error message: "No deductible item with matching amount sign".

Reproducing the Issue
Go to the Payment Management workcenter.
- Go to the Payment Allocation view.
- Open the Payment Allocation which has a positive amount in Open Amount.
- Click on Action > Apply discount or credit and add the negative amount to balance it.
You receive the error message: 'No deductible item with matching amount sign'.
The option Action > Apply Discount or Credit cannot be used for this scenario.
You can correct it only by using the subtab Allocation to G/L Account or Bank Charges, etc. to correct the Open Amount to 0 EUR.
