This specifies the name of the code table which contains valid entries for this Domain Definition. If the domain definition represents a hierarchy of code tables, the name of the lowest code table in the hierarchy should be specified as the code table name.
For fields for which a code table has been specified, the client application will display a drop-down list of valid values for the field if it is editable, or the code table translation for the field if it is read-only. In the case of a code table hierarchy, if the code table field is editable, n-levels of drop-down lists are displayed, where n is the number of code tables in the hierarchy. Only the first level is populated and a selection must be made to populate the next level in the hierarchy. For a read-only field where the code table is a hierarchy, the translation for the lowest level code table only is displayed.
This option is only valid for Domain Definitions which have been defined in terms of one which has theCode Table Root option set to yes.
