How to add a new field group and assign custom field to it?

Hi.

I Added a new field in Fixed Asset (tab ANLU, Screen 9000). It works almost fine, but it is not poperly displayed.

As i can see the (display)configuration is derived from T082b, t082f and t082g tables.

These tables are maintained in SPRO as "field groups".

I can change the rules of a field group, however I can't add a new group.

The question is how can I add a new field group and assign my new field to it.

Thank You.

Łukasz.
