Creating a Sort Specification for a Static List
You can define a Sort Specification on a list to override the sort specification that is defined on the business component. The default value for the Sort Specification property in a list is empty, so Siebel CRM uses the sort that is defined on the business component. It uses the Order By field in a Type to sort the list of values in ascending order, by default. If the Order By values are empty, then it sorts the entries for the Type alphabetically in ascending order according to the Value field.
You can specify a sort specification on a static list to modify this behavior. This modification applies only to the static list. A sort specification on a list object sorts values in the static list that references the list of values in the PickList Generic business component.
