Additional comments are not capturing on activity log for one of Case management scopped application

[sony8]

I am working on ServiceNow case management application where I built a new scoped application SCH.

For our new scoped app the additional comments are not capturing in activity log still it was enabled from form layout and configure available field from filter activity on the form

Tried many ways to debug but not able find the root cause why additional comments are not getting capturing on activity log in my scoped app SCH.

If anyone has any idea please help me.

Thanks in advance.

Did you extend your custom table form another table or did you create it from scratch?

Are you 'additional comments' a journal field, or a regular field?

[sony8]

I have created custom table by extending case management table. Additional comments is a journal input field coming from task table.

In that case I would create a case with NowSupport, since this is basic OOB functionality. A journal field should (by default) be added to the activity log, because it disappears after you save it.

The field I am able to see on my custom table form when I update it. It was not capturing on the activity log. Is this expected behaviour for custom table which is extending from another table?
