Incremental need a full backup to work, is a synthetic ok?

Hi, in the doc it say:

Backup Exec adds the time of the backup to the Backup Exec Database only if the full backup job completes successfully. If it does not complete successfully, subsequent differential or incremental backup jobs back up all of the data instead of only the data that changed.

Does a synthetic backup that complete successfully will make the next incremental backup work, or it really need a full backup?

thank you,
