Purchase Order - Quantity Release greater than Quantity Agreed

Dear all guru's,

 

i have a blanket agreement that can be released even if quantity release is greater than quantity agreed but amount release are below amount agreed. based on that case, i have several question to ask:

1. blanket release are referring to what in blanket agreement, whether Amount Agreed or Quantity Agreed?

2. is there any setup which i can use so i can choose whether referring to Amount Agreed or Quantity Agreed?

 

Regards,

Suryadi
