Several bill of material items may have the same value as a reference point however only one network activity may have this value. During allocation, the system checks whether the reference point in the selected network is unique.
It is possible to use generic entries for the reference point in network activities. However, in contrast to earlier versions (before Release 4.6), you must define the generic reference point in Customizing first. For instance, you have used reference points b12, b13, b14, and b15 in BOM items and want to assign all these items to one activity. You can define a reference point b* or b1* in Customizing and assign it to the activity. All of the BOM items are then assigned to the activity.
