After you have opened a screen in the Screen editor, right-clicked a screen field (a.k.a. entry field) on it and chose Properties in the pop-up menu, the Screen object properties window opens. On the Advanced tab in that window, you'll find some practically redundant and/or rarely used settings.

Click here for information on how to edit screen object properties in general.
On the current tab you'll find the following settings:

Field group

For Axiell Collections field groups should be defined in the data dictionary (the .inf), never here on screen. Any setting here will be ignored.

Occurrence

This property is not relevant to Axiell Collections and will be ignored.

 

Zoom screen

Axiell Collections ignores any zoom screen setting here. Instead, specify a zoom screen for the associated linked field in the data dictionary.

Zoom/edit screen

Axiell Collections ignores any edit screen setting here. Instead, specify an edit screen for the associated linked field in the data dictionary.
