AUFNR - VBAK / Internal order in header of sales orders
I have this problem:
I have a sales order with 20 items; I have to insert the same internal order for each item ..
I'd like to insert internal order in header of sales order, like WBS.
However I Have it only on item.
Can I insert internal order in header of sales order?
In VBAK there is the field AUFNR but in Header I don't see it.
Can you help me?
