The form is used by a company that provides support to its own users — an accounting firm, a software company and similar — to process the support requests (ZZP) that users enter in the Support form. It is part of the Ticketing module and is shown only to companies subscribed to that module.
The form is not in the menu: it is on the Brix home page, which you can return to at any time by clicking the Brix logo in the top left corner.
About filters and finding data in lists
