What causes this issue?

Either a network activity with the BOM item's reference point does not

System Response

Reference points are used to assign BOM items to network activities. BOM
transfer (transaction <LB>CN33_N</>) automatically assigns a BOM item
with a reference point to a network activity with the same reference
point. Automatic assignment is not possible because a network activity
with the BOM item?s reference point does not exist.

How to fix this error?

1. Add a new network activity with the required reference point
(transaction <AB>CJ20N</> with selected project).
2. Re-explode the current BOM version.
Or
1. Change the BOM item?s reference point if it is incorrect (<LS>Manage
Bill of Material</> app with selected item).
2. Re-explode the current BOM version.
