Activate Field

You must activate fields using ActivateField prior to executing a query for the business component.
By default, fields are inactive except when:
 They are displayed on the applet and the business component is the instance on which the applet is based.
 They are System fields (which include Id, Created, Created By, Updated, and Updated By).
 Their ForceActive property is set to TRUE.
 The method ActivateField has been invoked with the FieldName.
 They have the Link Specification property set to TRUE.
After fields have been deactivated, the business component must be reexecuted or the application crashes.
