A check box at the bottom of several tabs (on the Customer window) lets you view child items associated with Journals, Follow-Ups and Trouble Tickets.

When the check box is selected on the Customer Summary tab:
All child/nested retained Journals, Follow-Ups and Trouble Tickets are displayed in the lower grid for the customer.
When the check box is selected on the Journals tab:
All child/nested Journals, Follow-Ups and Trouble Tickets are displayed in the grid.
When the check box is selected on the Troubles tab:
All child/nested Trouble Tickets are displayed in the grid.
By default the check box is cleared; it needs to be selected every time a customer window is displayed in order to work.
Note
Selecting this box may cause a large amount of data to be returned and can affect system performance.
