How to make a single payment for different open items with same due date

Hi,

I have created a payment method and selected "Payment per due day " option in payment method company code settings.

Even I have selected that option, Payment will not happen grouping for the items with same due date

for ex : I have two open items with one due date and another open item with another due date so when I am trying performing F110 system should make a single payment for the item with same due date and seperate payment for another item.

But system making single payment for all items

Could you please suggest anything how to make a seperate payment with due date.

Regards
