Configure the default Portal permissions relevant to the Ticket module.
You can configure permissions for your Ticket Module under Configuration > Client Portal > Ticket permissions.
Activities - This section allows you to select the level of visibility you want to provide for activities which are linked to a ticket in the portal. You're also able to designate whether clients are able to create their own Activities, such as emailing your team, through the portal.
Tasks - This section allows you to select the level of visibility you want to provide for tasks which are linked to a ticket in the portal.
Fields - This section allows you to select the project-related fields you want to share with users in the portal. It is important to note that disabling fields will hide them from both View screens and List screens in the Portal. You will find that disabling some fields, such as Status, will cause the entire column to be removed from the list screen, as well as any related filter options.
