I maintaind BOM......for main material item categorey group is (Lumf) and subitems (Norm).
My req is....when i entered the main mateiral in sales order ...system should pick subitems
finally..i need to see main component and sub component in Slaes order
For BOM, you can use item category groups LUMF and ERLA. When you are using LUMF, the main item is priced and the subitems are not priced.
When you use ERLA, the main item is not priced where as the subitems are priced individually.
You can choose any one of the above scenario depending on your requirement.
Also, use the requirement 5 (Sales and Distribution) for BOM to explode.
