Today User raise a problem that quantity correlation function can not be used in delivery, but can be used in sales order, so I did some testing and summarized here.
Quantity correlation function is when you change quantity in high level item, quantity of sub-item will be changed in proportion automatically.
There is two factors have effect on quantity correlation function.
- Sales BOM linkage (VBAP- UEPOS), items have high-sub item link.
- Delivery group (VBAP- GRKOR)

In Sales order (Sales BOM linkage and delivery group can be updated manually)
- Sales BOM linkage existed with delivery group, quantity correlation function is active.
- Sales BOM linkage existed without delivery group, quantity correlation function is active.
- Delivery group existed without sales BOM linkage, quantity correlation function is inactive.
In Delivery (Sales BOM linkage can be updated manually, delivery group can not be updated):
- Sales BOM linkage existed without delivery group, quantity correlation function is inactive
- Sales BOM linkage existed with delivery group, quantity correlation function is active.
- Delivery group existed without sales BOM linkage, quantity correlation function is inactive.
Major difference is quantity correlation function is
inactive in delivery if no delivery group maintain even Sales BOM linkage is existed, debug result as below:
SE38: MV50AF0K_KORR_MENGEN_AENDERN, there is a check of delivery group.
“CHECK xlips-grkor > 0.”
Conclusion: Sales BOM linkage is foundation of quantity correlated function, but if you want to active this function in delivery, you have to use delivery group at same time.
PS: Automatic Sale BOM linkage and delivery group function are control by item category (VOV7)
