Calculation of due date while creating voucher

Hi,

While creating voucher system calculate due date based on payment terms. Supplier master having payment term as A and while creating purchase order have changed the payment terms from A to B manually but in supplier master it is still A.

1. When creating voucher which payment terms system use to calculate the due date for both basic item and landed cost lines. Will it fetch from Supplier master or from defined in purchase order.

2. When adding new line as option 4 which payment terms system use to calculate the due date. Will it fetch from Supplier master or from defined in purchase order.
