What causes this issue?

If the activity <ZK>Find Undefined B Segment and Implicit Merges</> is

control</> may now have become obsolete.

How to fix this error?

In the activity <ZK>Maintain B Segment Merges</>, obsolete entries have
a red traffic light symbol. You need to either delete or explicitly
accept these entries.
&ADDITIONAL_HINTS&
Entries for B priority control are package-dependent, but are deleted
only during initialization. Entries that have become obsolete get an
indicator 'O' in table <NP>CNV_20100_BPRIO</>.
