What causes this issue?

In order to get back to the most up-to-date status after restoring a
database backup (which is, after all, an older version of the data),
you must import all changes since the time of the last backup again
(Roll Forward Recovery). As this is done using the log files, you must
must have complete back ups of all log files that have accumulated
since the last database backup.

System Response

If there is a gap in the sequence of the log files, it is not possible
to restore the database to the most current status using the existing
data backup, if errors occur.

How to fix this error?

If you are missing a log file, perform a complete data backup as soon
as possible (for example, using the DB13 planning calendar). You should
also analyze the error that prevented the archiving being carried out
correctly and eliminate the source of the error (for example, a faulty
tape drive).
