Linking comments between tables
It is possible to show comments from related records on a parent layout.
Lets take an example. Say you had a one-to-many relationship where an organisation had many users.
If you enabled parent comments you would be able to see the comments that have been made on a user layout on the related organisation layout.
Enabling parent comments
To enable parent comment aggregation you need to go to the child layout settings and choose the parent table from the dropdown.
