Say that there is a 5 unit sales order. At first step, 3 units are delivered by VL01N and is billed by VF01. At the second step the remaining 2 units are delivered by VL01N and billed by VF01.
Which customizations should we do for this? I mean using a sales order as a reference two times(Sales order: 5 units / 1st delivery: 3 units / 1st billing: 3 units / 2nd delivery: 2 units / 2nd billing: 2 units). Are the customizations at the item level and how can I do it?
Thanks in advance.
