Inserting work fields into a report
With numerical work fields, the attribute for the number of decimals must be set manually by the user, using the Crystal Reports format editor.
If you are using a version of Crystal Reports earlier than version 9 or higher than or equal to 2008, the display attribute for DATE and TIME types must be set manually by the user, using the Crystal Reports format editor.
If a work field's type has changed, the effects of the change are propagated by starting again the Crystal Reports Designer: the interface is then regenerated and the fields automatically updated.
