Creating keys in a repeating form or section

In the Project Explorer, select the Forms and Transactions Explorer bar.
Select a repeating form or section, and select the Design tab.
Right-click the row of an item, and select Keys.
The Keys dialog box appears.
In the Data uniqueness for selected keys section, select one of the following:
- None —Key items appear in a drop-down list in the summary view of a repeating form as navigation aids. The key items are not used to enforce uniqueness of key values across instances of the repeating form.
- Individual —Each key item must be unique across all instances of the repeating form or itemset in the InForm application.
- Group —The combination of all key items evaluated together must be unique across all instances of the repeating form or itemset in the InForm application.
In the Key selection section, move the key items from the Items available as keys list to the Selected keys list.
If you are creating keys for a repeating form, and you selected Individual in the previous step, select the Unique checkbox for each item to designate as a unique key. (In a repeating section, the Unique checkbox is selected and disabled for all selected key items.)
Note: A set of key items for a repeating form can include both items that are individually unique and items that appear in the drop-down list for navigation but are not used to enforce uniqueness. The key items can come from the repeating form or from a non-repeating section in the form.
To change the order in which the items appear in the InForm application in the drop-down summary list of a repeating form, select an item and click the Move Up or Move Down button. Repeat this step for each item you want to move.
Click OK.
