Define data as read-only
This saves disk space when used on file process data by associating a single copy of the file per process for all closed actions and closed requests.
✏️ Note: An action’s OUT and INOUT parameters using data declared as read-only will not be updated.
⚠️ Caution: In general, do not define EFORM appplications'
FORM_DATA elements (which contain the data of a form) as read-only.
