For all attributes that can be modeled as a multi-segment key, such as Item Number or Account.
All key flexfields use the direct-entry method. (OMS-74055)
Only key flexfields with Validation set to Full should enable the List lamp. (OMS-74056)
Invoking a List of Values in a flexfield allows for entry of a combination-level List of Values. (OMS-74057)
Invoking Edit Field in a flexfield expands the field to allow entry of values in individual segments. (OMS-74058)
EXCEPTION: For a flexfield that allows dynamic inserts, Edit Field and List invoke the same window because it is irrelevant to the user whether a particular combination has ever been entered before.
Do not code any special visual indicator or activation button for key flexfields. The field should look like any other text item. (OMS-74059)
