Customer Payment terms

Hi,

I have created new payment terms. I have assigned the payment terms to the customer master data. I have created sales order(giving the new payment terms there at) and created billing document(giving the new payment terms there at). I could create both sales order and billing document successfully. I am now trying to process the open itme through F-28 and here i observed that cash discount is not getting picked up as expected.

Please let me know the probable reasons for the same. Thanks in advance.

Regards,

S.Sumana
