Data Schema Editor Characteristics Tab

Use the Data Schema editor Characteristics tab to define valid dates for calendar-type characteristics and to define enumerations (also known as drop down list values) for drop down-type characteristics.

Note:

You can define valid values for characteristics at two different levels: at the schema level (general) and at the specification level (specific). Design Studio evaluates the values defined for characteristics from the general level to the specific level. For example, the characteristic properties defined at the data element level (defined for data elements in the Data Schema editor) are overridden if you define properties for the same characteristic at the specification level (properties defined in the Specification editor).

See "Specification Editor Layouts Tab" for more information about defining characteristic attributes at the specification level.

Do one of the following: Click the Entity link to create and use a new specification. Click Select to use an existing specification. Click Clear to remove the selection.
Query	If you selected Query in the Drop Down Options field, you can populate a drop-down list with the results of the query that you define. Do one of the following: Click Parameter to create and use a new query. Click Select to select an existing characteristic for the query parameter. Click Clear to remove the selection.
