ADM Addenda : Enabling columns for new records only
 

Enabling columns for new records only

Introduced:

OpenEdge R10.1C
SmartDataObjects and DataViews have a new UpdatableWhenNew property that accepts a comma-separated list of columns that can be updated only for new records.
DataVisual objects support a corresponding new EnabledWhenNew property that specifies visual fields that should be enabled only in add or copy mode. The DataVisual property inherits the value from the UpdateTarget by default, but can also be set to a comma-separated list of fields.
