Filter List Dialog Box (Model Designer)
The purpose of the Filter List dialog box is to help you create a list from a set of available values that is too large to be navigated easily using a drop-down list. The available values may be the set of distinct values for an attribute, or they may be the instances of an entity defined in your model. Model Designer and Report Builder open the Filter List dialog box when you click the no values selected link next to a filter condition in the Filter Data dialog box.
For attributes, the Filter List dialog box is used if the attribute's ValueSelection property is set to List. In this case, the Available data list displays all distinct values for that attribute. To help find a specific value, you can type a word in the Filter text box, and then click the Filter button.
For entities, the Filter List dialog box is used if the entity's InstanceSelection property is set to List, FilteredList, or MandatoryFilter. If the property is set to List, the Available data list displays all instances of that entity, and the dialog box behaves the same as if it were displaying distinct values for an attribute. If the property is set to FilteredList or MandatoryFilter, no instances are displayed initially when the dialog box opens. Instead, when you click the Find button, you can create a filter that will return a subset of the available values. This subset will be displayed in the Available data list. You can add one or more values from this set to your list, and then repeat the process until you have selected all of the values that you want to include.
When you click OK, the items in the Selected data list are displayed in your original filter.
