Need to add a new field in Tickets

[harift]

Dear Team,

I want to add a new field for tickets like type, state, and queue. It must be a mandatory field, and it must be visible for all tickets, including auto-created, phone, or email tickets. I heard that it can be achieved by adding a dynamic field.

The new field is for marking the services that we provide, like networks, hardware devices, etc. Please help.

You really should read documentation. Adding Dynamic Fields is straight forward.

If you need to populate it with some values when parsing emails, and those emails got some header/information that you can use, look at postmaster filters too.
