Description
Provides a two-column table of validation data statically defined within the object itself for validation lists used through the Field_Value_Table field property in DataDictionary objects.
Sample

Object oTerms_Table is a DescriptionValidationTable
Procedure Fill_List
Forward Send Fill_List
Send Add_Table_Value "NONE" "None established"
Send Add_Table_Value "COD" "COD"
Send Add_Table_Value "NET30" "Net 30"
Send Add_Table_Value "NET60" "Net 60"
Send Add_Table_Value "NET90" "Net 90"
Send Add_Table_Value "PREPAY" "Pre-payment required"
End_Procedure
End_Object

Class OrderHea_Data_Set is a DataDictionary
Procedure Consruct_Object
Set Field_Value_Table Field Orderhea.Terms to oTerms_Table
End_Procedure
End_Class
This is an object for assignment in DataDictionary objects to database fields with the Field_Value_Table property. It provides both values for insertion into the database and descriptions to explain each value. It is the superclass of a hierarchy of more-capable and -complex validation classes, but is usable in its own right in simple, static situations.
If the Validate_State property is set to False, entries are permitted that are not in the list; in its default True state, it requires an entry that matches one of the existing table items. If the Static_State property is set to False, the list will be filled every time the table is activated; in its default True state, the object is loaded with its list only once in each session.
You can use Find_Code_Description to retrieve the description for a given code in the DescriptionValidationTable.
Note
If you use a cWebCombo or cWebColumnCombo with a DescriptionValidationTable or CodeValidationTable via a DataDictionary, the default will display the Code descriptions.
