Can't enable audit on Assigned field

[Raphael4]

Hi,

I created a child table from CMDB_CI called u_parking_spots.

I'm trying to enable auditing on this table, I managed to enable some field but there is one I can't: Assigned. 
To do so, I followed the documentation but the system still doesn't let me do it.

Please see the screenshot below:

Any idea?

If you enable audit table, then all fields in that table will be audited OOB.

Please see below to enable audit on table

Agreed,

that's the exact documentation I followed, However when I look at the audit history related list I don't see the Assigned field record.

Please navigate to System Dictionary of Assigned field and turn on audit.

1. Navigate to System Definition > Dictionary.
2. If necessary, customize the list view to include showing the Attributes column.
3. Navigate to the table and field (column) you want to whitelist.
4. In the Attributes field, enter audit=true.

Regards,

Sachin

Thank you for your quick answer.

Unfortunately I can't modify the attribute either.
