Incorrect line items in delivery

Hi All,

I am facing a strange issue with creating delivery. I have created sales order with 45CS. There are 43 CS in stock and hence sales order is confirmed for 43 CS. I see one line in schedue line tab for 43 CS.

But when I deliver this order, I see 2 line items with delivery qty of 43 instead of 1.

Any idea why delivery is splitting into 2?

Please advice.

Thanks.
