Work notes/Additional comments field is not visible.SummaryFor certain records, the work notes/additional comments field is not visible. Additionally, the activities filter will not show any updates, and the count will show as 0.ReleaseAll supported releases.Instructions1) First, check the ACLs for those fields and make sure there isn't an ACL preventing the view of the field. ACL debugging tools Note: ACLs should have no effect on update count. 2) A common cause is an invalid entry in the sys_audit_relation table. Fields that are not modified in a record will show up fine in the activities filtered, such as created on & opened on. Perform the below steps to validate which entry in the activity log is causing this issue and to fix it: Navigate to - https://<instance>.service-now.com/sys_audit_relation_list.do?sysparm_query=documentkey=SYS_ID_OF_RECORD&sysparm_view=2. Take a backup in XML format of the list3. Delete all the entries.4. Reload the form and now validate if you can see the work notes/additional comments and the activities filter is showing the updates.5. Now modify the XML so that it loads one update at a time on the record.6. The update which breaks the work notes/additional comments and the activities filter fields need to be removed and verified. 3) Another cause could be the maximum number of entries the system shows in the activity formatter. Note: This should also have no effect on update count, just visibility. In that case, you need to edit the 'glide.history.max_entries' system property, but please review Difference between "glide.stream.max_entries" and "glide.history.max_entries" properties for more information before making any changes.Related LinksAdditional Comments and Work Notes are incorrectly placed where the Filtered Activities are located
