The Service Feasibility widget allows you to quickly determine a route and save the results to either a feature service or CSV file. In order to use the Service Feasibility widget, a network analysis map service is required.

To configure the Service Feasibility widget, complete the following steps:

1. Add a new service feasibility widget to your web application, and edit the widget.
2. Configure the widget using the following parameters:

   Parameter	Description
   Closest facility service URL	URL of the closest facilities REST service. This service can be a hosted network analysis map service or the ArcGIS Online Closest Facility service.
   Facility search distance	Defines number of access points that are considered when determining the route.
   Impedance attribute	List of impedance attributes.
   Default cut off distance	Defines a maximum cutoff distance.
   Custom attribute parameter values or Travel Mode	Parameters from the closest facility task. When setting these parameters, you can configure the default value or allow a user defined input of the influence. You can choose to us your organizations travel modes for a predefined set of parameters.
   Attribute parameter value lookup	Comma delimited string of closest facility attribute parameters.
   Enable Selection Layer	Check this option if you want to find features along the route.
   Selection layer	Layer that will be summarized along the route.
   Field to be displayed in business list	Field from the Businesses layer that will be displayed in the output summary.
   Buffer distance to generate service area	Distance used to create the route's service area buffer.
   Buffer units	Units for the buffer distance.
   Access point layers	Layer or layers that will be used to determine the nearest location to an input point.
   Route result label	Label to display in the route result box.
   Route length conversion units	Unit to convert the route results in. Default will used the value returned by the service, which will be in map units.
   Route result expression	Expression to be used to display the route result. This uses the eval function.
   Route result unit label	Label to display in the route result.
   Result unit label position	The location in the results (before or after) where the route result unit label will be presented to the user.
   Rounding option	The number of decimal places the route result expression will be rounded to.
   Target layers to save results to layer	Layer or layers that will save the results of the closest facility service.
   Selection layer	Layer to save the resulting features from the closest facility selection layer.
   Route layer	Layer to save the route results in.
   Field to save route length	Field in the route layer to save the route length.
   Field to save selection count	Field in the route layer to save the count of features in the selection layer.
   Field to save Route result expression	Field in the route layer to save the route display, if you use a expression, this will be different than length.
   Route-Selection attribute transfer	When enabled, ability to save a value entered on the route to each saved selection feature. For example, add the proposed route name to all businesses along the proposed route.
   Route layer field	Field in the route layer to transfer to the saved selection features. This parameter is only visible when the Route-Selection attribute transfer is enabled.
   Selection layer field	Field in the selection layer to include the transfer the route layer field attributes. This parameter is only visible when the Route-Selection attribute transfer is enabled.
   Export to CSV	Determines if the business results will be saved to a CSV.
   Allow barriers	When enabled, the user can add point, line, or polygon barriers for routing.
   Point barrier symbol	Symbol used for the point barriers.
   Line barrier symbol	Symbol used for the line barriers.
   Polygon barrier symbol	Symbol used for the polygon barriers.
   Point location symbol	Symbol used to display the resulting point locations to the user.
   Route symbol	Symbol used to display the route to the user.
   Buffer symbol	Symbol used to display the route's service area buffer to the user.
   Image	The image used to highlight a selected result to the user. To specify your own image, click the image and select your image.
   Height	The height of the highlighted image (in pixels).
   Width	The width of the highlighted image (in pixels).
   Timeout	The number of milliseconds the image will highlight the selected results before the animation times out.
