Hello @Akhila P 

I would recommend checking out the eBook provided with the lab activity which is always helpful.

For step 5, a variable with type "Requested for" name "Remote employee name" is needed which is referencing to user table with filter as company is "HandHeld Holographics (HHD)" and default value as null. 
For step 6, you need to create entry under Rule base section which is like if user select some option on main form, then particular catalog item should be showcase further.

I strongly recommend having a look on eBook you got while enrolling lab. If still issue do post on community, we are there to guide you as best as possible.

If my response has helped you hit helpful button and if your concern is solved do mark my response as correct.

Thanks & Regards

Hi @Akhila P ,

Cascade variable refers to the functionality that allows values entered for variables in the initial order form to be passed to the equivalent variables in the ordered catalog items. This means that if a user enters a value for a variable, such as a delivery location, on the initial order form, this value will automatically populate the delivery location fields on each of the ordered items if cascading is enabled. To use this feature, one must select the Cascade variables checkbox when creating the order guide and ensure that the variables on the catalog items match the names of the corresponding variables in the order guide. This approach simplifies the process for both the user, who does not need to re-enter the same information multiple times, and the administrator, who can ensure consistency across the order process.

This youtube video can give you a practical example:

Hi @Akhila P 

Cascade means to show the variable at another but created in another form. Like passing information from RITM to Sc Task. Rest @Viraj Hudlikar @Sandeep Rajput shared the link.

Hi @Akhila P ,

In Order Guide (typically in IT Service Management tools like ServiceNow), Cascade Variables refer to variables whose values are automatically passed from the Order Guide to the Catalog Items included in the order. This ensures consistency and reduces the need for users to enter the same information multiple times.

For Instance,
Primary Order guide form has a field Requestor's User Phone Number field and the Catalog Item included in the Order guide also has the similar variable. By default, the value won't get copied so user needs to provide the phone number on Both Order guide and Catalog item form. So, We use Cascade variables to copy the Phone number from order guide initial form to Catalog item form variable to avoid it.

Types of Cascading Behavior:
• Automatic Cascading: The parent variable value automatically updates the child variables.
• Editable Cascading: The value is prefilled but can be modified in the Catalog Item.
• Locked Cascading: The value is inherited and cannot be changed in the Catalog Item.

I hope this information will help.
