Cascading enables values entered for variables in the initial order form to be passed to
the equivalent variables in the ordered catalog items.

Cascading allows values entered for variables in the initial order form to be passed to the
equivalent variables in the ordered catalog items. For example, a variable on the initial order
form prompts the customer to enter a delivery location value. If you enable cascading, the value
for this variable then populates delivery location fields on each of the ordered items.

To enable cascading, select the Cascade variables check box when
creating the order guide. Then, create variables on the catalog items that match the names of the
corresponding variables in the order guide. When a customer places an order, the variables on the
ordered items inherit the values of the identically named variables in the order guide.

## Use a variable set {#ariaid-title2}

You can use a variable set with an order guide.

### Vorbereitungen

Role required: admin

### Warum und wann dieser Vorgang ausgeführt wird

Cascading variables require that the same variable be on both the order guide and the
ordered items. It can be useful to define each variable once in a variable set, then
assign the variable set to both the order guide and the individual catalog item.
This approach avoids duplication and ensures that the variable is the same in both
locations.

To use a variable set with an order guide:

### Prozedur

1. Create the variable set.
2. In the Variable Set form, create each variable.
3. Add the variable set to the order guide and to each catalog item involved.  
   Hinweis:  
   The individual variables in a variable set do not appear in the Order guide or Catalog Item forms. To view the variables in a variable set, open the variable set record.

## Hide cascaded variables {#ariaid-title3}

You can hide the duplicated variables on the Choose Options
screens to keep your screen clean.
When cascading variables, you can hide the duplicated variables on the Choose Options
screens, making these screens simpler.  
To hide duplicate variables on all screens after the initial Describe Needs screen in the
Service Catalog Platform UI, run an onLoad catalog client script.

    function onLoad(){
      var item = g_form.getControl("current_item");
      var guide = g_form.getControl("sysparm_guide");

      if (item == null && guide == null )
    		return;

      if(item != null && guide != null && item.value == guide.value)
        return;
      g_form.setDisplay('YOUR_VARIABLE_NAME',false);
    }

To hide duplicate variables on all screens after the initial Describe Needs screen in
Service Portal, use the isOrderGuide() method.

    if(g_service_catalog.isOrderGuide()) 
      g_form.setDisplay('variable_name', false);
